I have not tried that, but if the "spring" being discussed is the bonze flat
copper-colored metal part, it should be noted that one side-flap is wider than
the other. The wider side-flap has stonger spring action than the narrower
one. My suspicion is this unequal strength of the centering action is to
enable delayed uncoupling to happen properly. Thus, the knuckle can open up
without necessarily pulling the coupler body off center. Or something like
that.....

I see no advantage to assembling the coupler spring upside down. Was the
presenter doing it intentionally or accidentally?

I try to follow directions unless they are proven to be inadequate. So far, I
have not had any problems with the KD#5 couplers.
As stated earlier, the main problem with reliable coupling is the large
side-slop (called "lateral play" by those in the know) between the axles and
sideframes. I remove nearly all of the lateral play with small washers over
the axle ends. Newer models with pointed axles do not have this problem, but
it is common with older trucks of the ACE and Kinsman vintage.
