Apparently, that's the reason they deleted the scene of Old Biff fading from existence...because the Bobs felt that audiences wouldn't be able to understand how Old Biff could appear in 1955, when he was seen being erased from existence in 2015...
That and they couldn't really explain it. They had the chalkboard scene to illustrate to the audience explaining what is happening. But they had no way of explaining biff disappearing without doc and marty seeing it.

Agreed...they couldn't really explain the whole 'he was shot by Lorraine in 1996' thing on-screen. Though I suppose people COULD have simply figured out that Biff messed up the space-time continuum (like Marty did in BTTF1) and so was consequently erased from existence somehow.
