I don't believe we are required to agree with the rationale for all mechanics; those that can make the rules, do, and our job is to try to conform to get ahead.

And, I am also a former catcher that never got past the mental and muscle memory of taking the mask off with the right hand; I also swap immediately.

That said, here are some responses I have heard over the years to justify questions.

Mask; if you always have it in the correct hand, there will never even be a possibility that you would signal (particularly overhand or punch out) with the mask and lose it, or hit someone with it.

We alternate between innings to make sure there is no perceived favoritism by being closer to one dugout (and coaching staff) all the time.

We sweep the PP to see it; when a pitcher covers it again, she gets no benefit of doubt if there is an issue. We can also resweep it anytime if necessary; but setting a standard time makes it less apparent if we are watching one pitcher more than the other. We always do it between innings because that is the least obtrusive moment.

The mask is the most visible symbol of the authority of the PU; setting it down also can be perceived as setting aside that authority.
