Yes, that is what happens.  Observing the same phenomena, I put a current
meter in series with the battery.  When the machine is turned on, the
battery does indeed "charge" with a small current.  I seem to recall that
technically the lithium batteries used are not rechargable-- however, they
do seem to tolerate a small amount of reverse current.
