No, SRFI 34 says:

   (raise obj) Invokes the current exception handler on obj . The
   handler is called in the dynamic environment of the call to raise ,

   **** except that the current exception handler is that in place for
   the call to with-exception-handler that installed the handler being
   called. The handler's continuation is otherwise unspecified. ****

According to this, the continuation of the exception handler can't
be the ***same*** as the continuation of raise because the dynamic
environment is different (recall that the dynamic environment is
part of the continuation).
