I would say if it stays as the same texture, then it is the same texture. I'm almost 100% sure of that :)
Edit..
LOL. But not 100% sure. Sorry, I forgot about this...
It seems if you entitytexture (or paintentity, at least as far as texturing goes) something then that has priority over paintsurface. Try Paintmesh instead.
BTW. I think you can undo Entitytexture by using Paintentity with a textureless brush (just in case your entitytexture is for some reason a fait accompli).
