Qucik Question regarding a bunt attempt

[Odd Duck]

I am a basketball official and was asked if a baseball umpire ruled correctly...don't ask me why I was asked...who knows.

Batter has two strike...first base is open. Batter squares to bunt and offers at the pitch but misses completely (absolutely no contact with the ball). Catcher misses the ball...batter runs toward first because of the missed third strike...catcher throw is errant and runner/batter is ruled safe at first.

An arguement ensued that the batter should not be allowed to attempt to advance to first because it failed attempt at a bunt on strike three. Umpire ruled that since there was no contact, it is the same as a swinging strike and batter is allowed to attempt the advance to first because of the drop.

Sounds like the umpire got it right but what do I know. I know the basketball rules (although some coaches would argue that point) but not baseball.

Did they get this right?

Thanks,
