No, there's no such restriction. You can see examples of exactly this
in the "pricing engine" demo that ships with Jess; look at the rule
free-cd-rw-disks, for example. More likely the problem is you're
using the same variable name in both patterns, forcing them to be
unified, while matching some other slot to distinct values, forcing
them to be different -- i.e., you may have written patterns that are
impossible to satisfy.
