"Don't ask me why. "

There are three things:

(a) I don't know wether XG uses 64-bit doubles or 32-bit float. Given the high speed it might be 32-bit. They have only around 7 digits of precision adding/multypling may introduce rounding error (but up to the 4th digit?)

(b)it's a computer and things you expect are not true e.q. commutativity, i.e. a+b don't has to be the same as b+a. Usually only on the last positions.

So now the most probably explanation. Assume you have at ply x 2 (nearly) equal good moves. Which move is analyzed further might depend which core delivers results first or other small inaccuracies and that will have a small influence.
