Yeah, I'd be fascinated by that explanation. But atomic reads are silly.
What is the point?

One point is that it provides a memory fence. That's pretty much the only
point.

In 64 bit variant, also, InterlockedCompareExchange64 allows to atomically
fetch 64 bits, which is not guaranteed by other C-compiler means on 32 bit
machine.
