Yes.

1.  when the laptop is manually woken, it takes too long for the
wireless connection to be restored, during which time any network
membership change is lost, http://dev.laptop.org/ticket/9854

2.  in the time during which this happens, the laptop will idle again if
not kept awake, so that in the absence of human input it will never
succeed in showing updated network membership,

3.  the laptop is not kept awake to listen for possible changes to the
network membership, we choose to suspend instead.
