Looking at this again, I'm not certain there is a bug. You are displaying the variable assignments, but are you first applying the type variable assignments? Both must be used in order to instantiate the object term.

So, I guess the above question becomes: how come the FO matcher doesn't instantiate the type variables? Of course, this is a different question to why the HO matcher doesn't return matchers to the second lemma.
