Programs only move in zero seconds in three cases that I know of.

1.  book move.  The assumption is that someone/something has already spent
a lot of time in choosing these moves.

2.  forced move (only legal move).  There is no reason to search at all if
you have no choice, legally.

3.  Pondering.  These moves are not really made in zero seconds.  It just so
happens that all the calculation was done while waiting on the opponent.

Humans do exactly the same thing.  I have seen them make several 0-second moves
in a row.  I am not sure why you think this is a problem?
