This is a minor stylistic suggestion: when translating the mathematical expression (a < b < c), write it as (a < b) & (b < c). It has no effect on the outcome, but keeping the inequalities in the same direction makes the meaning more obvious. If you do this, your expression becomes (Y<1 & 1<X) | (X<1 & 1<Y) and it's clear at a glance what's going on. I think I originally read this suggestion in something written by Kernighan and/or Plauger, I can't claim credit for it.
