On one of my former bikes I did have my Ulock mounted in exactly the same way as you have it BST.

But it depends on bike geometry. Unfortunately for my present bikes, I have no choice but to carry the bloody lock inside my bike pannier. I dislike it on top of my back bike rack, for the constant rattling while going over bumps, etc.
