I think that's missing the point of the line in NEM about Soong's whimsical sense of names. "B-4" is supposed to be a pun on "before," because he's a prototype.
Besides, what would the "B" stand for if it were just a dry classification number with no pun involved?
I got the pun, but for there to be three earlier prototypes... it just fits so well. Maybe B-4 being the first working proof-of-concept was a happy coincidence.
Perhaps the A's were a positronic brains which never functioned at all, Soong went back to the drawing board and came up with the B-series.
