My understanding, from things I've read in the past, is that there seems to be a connection between this and your frame rate. The higher your fps, the more exaggerated the physics become and the more of a problem. So on the consoles, which generally run at a lower fps, it's not generally going to be an issue. Maybe once in a while, though. However, on a PC running at a significantly higher fps, it can become an issue.
I think your right, I play on 360 and the bro plays on PC and when we get together we test bugs to see if there is a difference between PC and console. This was the first bug we tested and I had stuff fly off my table at Breezehome, he had stuff fly off the same table but at a more exaggerated rate.( he was killed by a flying cup to the head

) Tested 3 times each and the results where the same all three times, I would have stuff fall off the table where as he would have stuff flying all over the place like shrapnel.
