The fifty move counter will have absolutely zero bearing on the strategy in
either of those two positions. It will be reset long before it even approaches
50. The strategy will be the same whether the fifty move counter is 0 or 10.
Most probably, it will be reset on the very next move in both of those
positions.

My point is, to accurately answer your question as you have explained it to me,
you have to hammer out these details like, "does the fifty move counter change
the strategy in this position?" If it does -> different positions. If it doesn't
-> same position. Isn't that how you justified mirroring and not counting
"duplicates"? The mirrored positions had exactly the same strategy, just like
the positions I showed. Even if the fifty move counter is at 40 it probably has
no bearing on the optimal strategy in those positions.
