There is a logical reason, but people do not always agree with it.

The reason is that once the program has finished computing, what you see on the
screen is "mate in 6", and if you check with the board position, it is indeed a
mate in 6 from this position.

I did not like the idea of announcing a mate in 7 when actually the position on
the screen is a mate in 6.

What do you announce to your opponent when you discover a "mate in 2"? You play
the first move and you tell your opponent that he is mate next move (mate in 1),
not in 2 moves.

Actually I have been told that announcing to your opponent that he is soon going
to be mated is impolite, so I should not display anything in this case! :)
