If an inferencing state with the same name already exists (as compared using eql ), then the value of if-exists determines what happens:

:error

A continuable error is signaled. Invoking the continue restart causes the existing inferencing state to be returned.

If set-current-p is non-nil, then *inferencing-state* is set to new inferencing state.
