Short answer: Yes, it's correct.

Long answer: The "Should this message be signed?" decision involves
several tests, one of which is comparing the MTA name against a list you
can provide that (presumably) contains the names of MTAs whose mail should
be signed. By default this list is empty. The log entry you're citing is
simply saying "I didn't find my name in that list."
