The rule should be identical to previous cases
Is it so hard to understand?
In previous cases a lot of draws were claimed wrong by your definition and there
was no problem with it so you cannot change the practical rule.
If castling is not allowed in a tournament even if it is against the written
rules then allowing castling in the last round is also unfair.

You cannot decide for the reason for other person.
Almost no program claims a draw by the fide rule by your definition and I also
not plan to change my program to do it correctly.
Movei print the move that it plays to force repetition and immediately after it
prints 1/2-1/2 movei->draw by repetition.
movei is refusing to play later.
I see no reason to change it and to add the word claim and not give the mover
because I think that it is clear enough.
I could change the program not to make the move and claim a draw before it by
only claiming that it is going to make the move but I am afraid that in this
case some interfaces may not understand it and complain that movei lost on time
and I guess that if I try not to make the move on ICC and claim a draw based on
intention to make the move I am going to lose on time.
This reason is for me good enough not to implement claiming a draw based on
intention to make a move but only immediately after making the move.
Here is an example for the way that movei claim a draw in a game
