Double Registered??

I don't know, seems to me that Verona is basing her opinion on some pretty solid facts - AQHA.
Tobiano is a colour, not a breed, right?

Look, the Jockey Club, the AQHA, and the APHA are all intertwined. There are AQHA horses that are far more TB than QH, TBs that are double registered JC/APHA, and APHA horses that are heavily crossbred into AQHA lines.

It will never be as simple as testing to make sure that tobiano's do not get into the AQHA. ANY horse with tobiano ANYWHERE in it's linage is not nor ever will be accepted by the AQHA.

I would hardly be the one to state that AQHA horses are purebred. The foundation for them came from alot of different breeds. Like the Paint came from Quarter horses and were bred for that trait.
But saying a paint does not have AQHA heritage seems odd to me based on the sole fact that AQHA does not recognize a COAT pattern. There was a time when Sabino Arabians were not elgiable for registration; not because they weren't purebred, but because of coat colour. I see the same thing with AQHA.

The reasoning for the majority of the mixing is exactly the same as the sabino Arabs: The AQHA didn't like the excessive white, so they were automatically sent to the APHA, who, at the time, allowed it. So there you now have loud colored Quarter Horses registered as Paints and it took a while before the APHA said screw that and the AQHA was forced to keep them. However, the majority of the owners of those horses did not go back and re-register their crop outs as AQHA and left them as Paints.

Then you get to horses like the OP's, who come from APHA lines, but did not inherit the white genes or just doesn't express them loud enough (and it's the APHA..they only care about how the horse looks, not it's actual genetic makeup). What if that horse is from crop out AQHA horses? Does that make it AQHA because it doesn't have a pattern? No. Only if the parents were double registered. Or like the OP's and it's mixed with AQHA and actual APHA tobianos. Then you are still left with a solid APHA horse that is separated into its own section.

Neither of the breeds are pure, so I suggest if you'd like a pure breed, you stick with your Arabs.

Drawing from your example, if you have offspring from two double registered APHA/AQHA horses, and you choose not to register with AQHA, it does not make that horse any less quarter horse IMO. It does, however, make it an unpapered quarter horse.

Can you tell me what characteristics are different between the AQHA and APHA breed standard? When you look at a horse, what conformational traits identify it as a SPB instead of a QH?

The Jockey Club is more than 100 years old and is the American registry for thoroughbreds, which was a breed developed in the 17th and 18th century. It does not, and never has, accepted quarter horses or paint horses in its registry who were not also 100% TB with Jockey Club registered parents. The fact that APHA recognizes some purebred TBs as paint horses is neither here nor there.

Appendix Quarter Horses aren't usually accepted by the AQHA with full QH registration. They are an added in section of AQHA. A horse has to earn rights to full AQHA registration.

The Appendix rules are shaky to me, but as only a first generation QH/TB cross are allowed, how can you say that the AQHA recognizes some /purebred/ TB horses?

I didn't say AQHA recognizes purebred TB's (although historically they did make exceptions for Joe Reed #3 and Oklahoma Star #6).

I said APHA does- I admit, I took this fact from Poseidon's post and did not fact check it.

^^^^ Beginning in 2005, the APHA required at least one APHA parent even if they (QH or TB) would have previously been eligible by meeting the color requirements, so QHxQH, QHxTB, and TBxTB cannot be registered with the APHA.

It is from the excess white rule. Not anything about overo or tobiano.
If the horse was AQHA x AQHA had to much white, and then got reg. As Paint
After DNA proof of the sire and dam that they are AQHA lines, then they can be double registered. Must have the DNA.
