Sorry, my mistake (and I thought I checked the example before posting, 
obviously made a mistake there as well).

I forgot the exact operational semantics for  reified constraint, in 
that it acts in a passive check mode only when its truth value is not 
known, and is imposed as soon as it is known it must be true. For and/2, 
it requires both sides to be true, so both constraints will be imposed, 
giving the same result as posting the two constraints directly

  X #> Y, Y #> X,

although the reified form is somewhat less efficient.
