I have no idea regarding the why as I only read A New Beginning (which I barely remember) and enough of the Power of Shazam series to realize they had hit the reset button (and I don't remember anything other then that).

As for why, everyone at DC had to know Zero Hour was coming down the pipe and someone felt the Captain needed a reboot. To test the waters the OGN came out March 1994 and based on sales became the foundation of the series which started March 1995.

IMHO the only reason the ANB Captain Marvel is part of Earth-85 is Zero Hour was in Sept 1994.
