The problem is that there in no other case does it seem necessary to instantiate a brain state in order to undertstand something.
Riding a bicycle. And you need to instantiate a brain state to know anything—instantiating brain states is what it means for a brain to know something. The explanation for “why it seems to be unnecessary in other cases” is “people are bad at physics”.
Or you can use a sensible theory of knowledge where Mary understands everything about seeing red without seeing it and the explanation for “why it seems that she doesn’t understand” is “people are bad in distinguishing between being and knowing”.
I mean, there is physicalist explanation of everything about this scenario. You could have an arguments on the level of “but people find it confusing for a couple of seconds!” against physicality of anything from mirrors to levers.

No, knowledge can be stored outisde brains.
Mary understands everything about seeing red without seeing it and the explanation for “why it seems that she doesn’t understand” is “people are bad in distinguishing between being and knowing”.
Or people insist by fiat that they are the same, when they are plainly different.
