No, it's done on purpose.

Announcing mate in 7 sounds like "I have found the solution of the problem, and
it's a mate in 7".

Announcing mate in 6 means: "I play this move, and then you are mate in 6 moves
(or less)".

I know it sounds more brilliant to announce a mate in 7 than a mate in 6, but I
prefer the second way.
