I think those changes may be more than a year old, but looking at the AQHA rulebook, yes, you can register a horse with white marking in the AQHA if you can DNA verify parentage (and the parents must still be in the acceptable registries), but the AQHA still considers it an 'undesireable trait' and is so noted on the certificate.
As for the APHA, I'm pretty sure the one Paint parent rule has been there at least 3 years...we bought our first Paint about 3 years ago and I remember actually reading the rulebook back then. I looked at the rulebook this morning and didn't see anything different.
The bottom line, though, is that you're right that there are a lot of dual registered Paint/QHs.
