Not really sure what they mean by that, but perhaps it's just an rough estimate of their current contract or expectations. Figure if it remains popular and the creators are able to keep supplying worthy storylines, I can't see any reason to not renew for another season if a current one is doing well.

Look at how ancient Spongebob is at this point. New ones are infrequent anymore of course, but they still show up now and then and Wikipedia suggests it has 188 after, what, 15 years? So maybe 137 is kind of a positive number, as long as we don't blow through them too fast. (But hard not to want more each and every week! lol)
