Is PMT_NIL a Valid Dictionary?

I was writing a QA test and decided to try,

 

self.assertTrue(pmt.is_dict(pmt.PMT_NIL))

 

and it passes.  I was just wondering if pmt.PMT_NIL is considered a valid dictionary object, as opposed to,

 

my_dict = pmt.make_dict()

self.assertTrue(pmt.is_dict(my_dict))

 

Just trying to get a better understanding and couldn’t find an answer.
