I believe that all sides of the SC except the top and bottom have 
solar panels on them and they indicated based upon current telemetry 
that they are there and intact.  While your logic could be also 
applied to the top or bottom (remember the omnis), I'm not sure it's 
spinning with those axis being exposed, more likely it's 
spinning "about" those axis.

A chunk of metal blown out from the top or bottom of the spacecraft could potentially 
be in ANY orientation, leading to "radiometer" forces on any axis.

I look forward to hearing from the controller team if this theory has already been considered.
