See, I was always taught not to guess off the bag; if the ball beat the runner, call the out. Everyone knows to make that appeal when appropriate, everyone knows that PU will answer if he sees the foot off.

This reverse handling seems awkward; the "off the bag" should be an affirmative ruling that was actually seen. I understand Tony's feeling of ruling the opposite of what BU "saw", as opposed to adding a piece of the puzzle.
