The robe already has 100% potency during the specific day, so there's no use of the obi anymore.

oh, and...
seemed like a valid question to me...

The summoners I've spoken to tell me that the obi has no effect on perpetuation or avatar blood pacts. I haven't tested it personally though.
I happen to have both the SMN AF2 body along with a few elemental obis for my blm. I can say 100% for sure they don't work together. Also the obi has no effect on BPs, at least as far as I can tell given their randomness.
