EXP Cap?

Weird, so the cap would just stop you from gaining exp at all? o.o''
Why that? Why not just make it so you get the most amount of exp that you're supposed to get? O.o

It was probably more likely an anomaly in the game code instead of a purposeful cap. Perhaps some part of the formula goes wonky at that point and defaults to 1 (or some mathematical equation that equates it to 1 when it hits a certain number). I couldn't possibly know the specifics, of course, but I highly doubt it was ever an intentional thing.
