I think it has something to do with relativity.

Think relative humidity rather than absolute.

The warmer air inside the box(piano) has less relative humidity than the 
air with the same absolute humidity outside of it.  Dew point is at the 
bottom of the temp/humidity chart, not the top.

BTW, I haven't seen a playable hermetically sealed piano yet. Some with 
very little air flow routes, perhaps, but none with none.
