I see no reason that the gelding should act like a stallion unless:
1) he was proud-cut or
2) he was gelded late, and/or bred mares before gelding
Has he ever been turned out with mares before? If he socializes well with other geldings, I wouldn't worry too too much about stallion-like behavior; stallions don't usually tolerate other males around, gelded or not. If they have been socializing over the fence and there have been no issues, I would go ahead and see if they do well together or not, that is, pen them together (with enough room that they can "escape" from one another, if need be) and keep a close eye on them for the first little while. Make sure you are around if something happens, so you would be able to separate them. It would be ideal to have at least one other person with you just in case.
About the pooping only in specific areas: not a big concern. I have a few horses that do just that, and they are turned out with mares no problem. And the nipping was probably the gelding "testing" the mare. Not a huge problem unless the nipping turns to biting or kicking.
About this gelding acting like a stallion... stallions LIKE being around mares, for the most part. Unless they have not been allowed to socialize with other horses, they should have respect for the newbie. (That is a major problem with stallions that are kept separate from other horses - they do not know how to act when placed amongst other horses.) The fact that your gelding has been with other horses is reassuring, it tells me that he's okay with being around other horses without acting like a dink.
A good indication of whether or not you'll have problems is if the gelding "roars" when there are mares (or other geldings, for that matter) around. It is a characteristic "stallion" move that they don't lose after gelding.
Bottom line is, I think the guy was full of it. He probably had a bad experience once with a proud-cut or late-gelded gelding, and then generalized from there. Try them together, and see what happens. I manage 36 head of horses at a ranch, and I mix and match genders (we only have mares and geldings, no stallions) without many problems. If there is a problem, then I just mix things up again, and try again. If you know your horses well enough, you should be able to tell who goes well together and who doesn't. I do have a proud-cut gelding on the premisis, (I didn't know it when I bought him) and he was fine with mares - his only problem was that he'd mount them when they came into heat - not good, so I now keep him with geldings only.
I hope this helps!
