Una corda: upright lost motion compensator?

This is a nice feature. I have seen a couple of other pianos with that feature, but I can't recall which ones.

I have an S&S model F console (sympathy accepted, but it's a family piano). I regulate uprights so that the bridle straps don't move the keys down when the una corda is depressed. But on this piano, all but one key moves down with the una corda, and this nicely removes the otherwise excessive lost motion.?
?
Bug or feature??
