Well that doesn't contradict anything that I have said :) My question remains - what do you mean by coherence? I argue that it is precisely the property that there is a consistent order of operations a single memory memory location so you can't say that Relaxed operations don't satisfy coherence.

You are correct. IIRC Coherency is the only property of relaxed atomic operations, as opposed of plain load/stores where concurrent modification and access is just UB.
