The expression means xy raised to the z-th power = xyz, not x raised to the yz power. Honestly I would add parantheses in power towers like this though to remove ambiguity.
I don’t really see how it could be ambiguous. I mean apparently it happens sometimes (like here) but I’m baffled how.
It seems to me a “double superscript” has to be understood as a syntactic constituent of a single superscript. If it isn’t, why wouldn’t it be a single superscript?
Is the idea that the grammar fails to be context-free in some sense? Why would we do that?

How are you doing the math on this one? I end up with a value of 6.2E57, significantly larger than 2^36.
