Exactly. In 2.13 (soon to be 2.14), you would do 
\new PianoStaff \with { \RemoveEmptyStaves } <<
...
>>
\new PianoStaff <<
...
>>

And only the first PianoStaff will be removed if empty.

And the two staves of a PianoStaff are only removed together (i.e. only if 
both the left and the right hand have rests), but not separately as you 
observe in 2.12.

Cheers,
Reinhold
