That's a strange way to interpret "separate," since both mechanisms
are joined with parameters.  Why aren't dynamic binding and
thread-local storage separate?  Our Scheme workshop spells out exactly
what the semantic problems are.  (Specifically, they occur when a
escape procedure created in one thread is invoked in another.)
