Is there a possible credible scenario with one TL at reverse, the other at cl, brake pedals pressed, where one does not want to stop?
No - it's incredible.
So, this might be a case for extending the ground spoiler logic to become:
A/C on ground
AND ((One T/L in reverse and other T/L in reverse or at or near idle)
OR (ground spoilers armed and both T/L at or near idle)
OR (one T/L in reverse and brake pedals pressed))
Excluding one at CL and one at idle, because that might happen with one engine shut down, even
not wanting to land.
Perhaps one should also exclude one T/L at TOGA, because it would again be too ambiguous.
Whether or not this makes more sense than changing training procedures and/or memory items is not my call to make.
I may write up all my considerations about ground spoilers and thrust reversers and thrust levers in more concise form (standing on the shoulders of PBL's "classic" paper).

P. S. To all those thinking we are defending Airbus at all costs: this should make it clear that we are not. No product created by mere mortals is above criticism, but it should be founded on more than saying "I am convinced non-moving thrust levers are bad!"
