I would assume it’s a matter of the system not staying within operating parameters.
It’s designed to run with a certain amount of clearance for other aircraft. And if you’re unable to keep the thing running within the safety parameters you set for yourself, that really is an issue—even if the margins are large enough that violations don’t necessarily lead to collisions (ie, as opposed to running with zero margin)
