Power off I doubt it, doing nothing could be just a question of perception as selecting OP CLB won't produce instantaneously climb thrust as such altitude especially if thrust has been significantly reduced just before selecting OP CLB.
But if you want to link a video to what you refer as a "French quirk" in the Airbus I'll be interested to watch it.

It is normal for the A/THR in level flight to reduce the thrust to match a speed reduction request, but once OP CLB is selected, the request is for climb thrust. Selecting a different vertical mode such as V/S could be different ...
I am used to FLCH/LVL CHG where full climb thrust is automatically commanded even if speed selector rolled back.
And this is not different from OP CLB.
