Maybe I'm being ignorant here but aren't the small rings just plain? If so, how a different size chainring would make a difference?

When the chain is derailed from the big chainring, it needs to land correctly on the teeth of the small chainring (and vice versa).

I found a good example that show your explanation below.

Show how the teeth is line up almost precisely when shifting from small to big.

If the teeth Is a little further forward or backward, it can “slip” until it hook into the chainring, this happen with mixing chainring.
