You're 100% correct, it's incredibly rare. I wouldn't be at all surprised if there are multiple reasons for its:
1. Boards rolling off of Capcom's production lines would only have hard the 910204 revision for two days prior to 910206 being issued. Since arcade PCBs are not fabricated in anything approaching the massive numbers of most end-consumer gear, it stands to reason that there wouldn't have been that many boards that managed to roll off the line with that version.
2. This is pure conjecture on my part, but if Capcom were anything like Midway, then they would have made upgraded revisions available to existing owners in the form of replacement sets of ROM ICs. If they didn't, there's also a high likelihood that existing owners of the early versions would have obtained updated ROMs from other owners or operators. Speaking of upgrades, it would be far more likely for an owner to upgrade to the latest version, not downgrade to a previous version, over the lifespan of the game.
Is it a pre-release game? Who knows. It could be that the majority of release-date documentation is based on the more widely-released version, which was on assembly lines for 8 days at most, rather than 2 days at most. It could be that some programmer or manager at Capcom jumped the gun two days before the retail build was ready.
At the end of the day, it's cool because it's incredibly rare, and it being pre-release or not doesn't take away from its coolness.
