The B+ connection could be to provide bias to prevent cathode stripping before the heater becomes effective. Not sure, just an idea.

Agreed. So far I don't see a reasonable explanation. I tend to think (as another poster said) it was simply some experimenter's ill conceived idea that wasn't expunged from the published schematic.
