I've buzzed the back of the saddle on my DH bike but on all my other bikes it hasn't been an issue. Interestingly, looking at that particular saddle it seems that the rails are closer to the saddle base than some of my other saddles, and the shape of the back/way the rails terminate seems to allow it to sit closer to the wheel than others. I hadn't put much thought into that before (whereas I had considered the stack of the seatpost head) - but apparently rail-to-saddle clearance is also a thing.
