Using a different nibble will give you different properties, not necessarily any better.

I actually convert the native BCD seed to binary form before taking the MOD in the Saturn version, so it does actually end up being the last few bits in this case. And I'm obviously no expert in PRNGs, either, but I believe your assessment is spot on.
