Yes I think this is a good point. The uni-directional wheels must have been at least relatively quiet in reverse. In the past I have tried running my own various models in reverse to see what would happen (and to try to see if I could get a new view on a solution) and the weights tended to delay before responding to gravity and sometimes did not so much "fall" as slowly return to their former position. If, instead of falling, they returned slowly as the wheel turned, then that is why there was no noise and no impact.

: Bessler stated that, during demonstrations, he would allow his wheel to be pushed or turned in any manner desired, stipulating only that the wheel must not be forced to rotate faster than the maximum speed for which it was designed.
: That being so, Bessler would have had no objection to someone turning his uni-direction wheel in reverse for as long as they liked.
: This raises a couple of questions: 1) Did the uni-direction wheel exhibit an overbalancing force when rotated in reverse? 2) Did the uni-direction wheel exhibit rim impact noise when rotated in reverse?
: IMO, if the later bi-direction wheels were composed of two joined back-to-back uni-direction wheels then, IMO, the one-direction design must have been silent when operated in reverse, otherwise the bi-direction wheels would have exhibited rim impact noise on both sides of the wheel.
: Furthermore, if the overbalancing force acting on the wheel was accompanied by unavoidable rim impact noise (Bessler said he couldn't silence the noise) then, IMO, the uni-direction wheel exhibited no torque (was balanced) when turned backwards. No noise = no torque.
: Question for those presently building wheel attempts: Can your design be turned in reverse without problems?
