It is unsat, but Alt-Ergo cannot prove it and returns unknown. This can be "fixed" in different ways, for instance moving the range assertions for x and yafter the distinct assertion!
This looks like it is usual intervalCalculus madness. I still have plans to migrate it to use the Domains interface instead, which might help here.
