The following play is the reason I bring it up.

A couple problems here with the way it was handled.
If you watch the celebration, the OC does physically direct her back to the plate (0:27). There's no other reason for her to reverse her direction.
That should have been the out (based on your response, Mike).
The tag that F2 put on the BR was with a new game ball the PU gave her (not a valid DB appeal and should have been ignored), HOWEVER,
after F2 makes the tag (and PU properly disallows the appeal), the next logical thing would've been "but blue, she missed the plate!", which WOULD be a proper DB appeal.
Except, in the 1.2 seconds it would take to say that, BR may have made it back to the plate.
