Not in principle, but in Gnu Go it does.  What Gnu Go does *not* do is
to check wether *one* certain move destroys the followup potential of
*another* point.  That is what happens in a general double sente
position.  If I play here, not only do I have a big followup, it also
destroys the opponents chance to get his point and his followup.

On the other hand if the same point has a great followup and reverse
followup value, we recognize it, since naturally the opponent can't
play on an already occupied point.
