As soon as the engine is rotated they begin to move away from being where they were set on install. At some point I suppose they return to the original position but don't know that for sure.

Grumpy02, your assumptions are correct. I recently did the timing belt job on my v8 4Runner. If Mattmaine1991 is just inspecting the timing belt, it will only line up when installing the belt. Once the engine is cranked, it will be tough to the get all the markers on the belt lined up.
That said, the top cam gears should have a mark on the house and a small divit on the gear. You can see them in the picture below:
There is also some markings on the crankshaft gear as well. The engine will need to be set at TDC before removing the belt. The cam gears or crank should not be turned independently while the belt is off. Probably going into more detail than needed.
Long story short, Mattmaine1991, if your engine is running without issue, you are fine. The paint marks on the belt are only used at the time its installed.
