I was saying the only reason I could think for a clone wanting to meet mando, is that the clone considered himself to be a mandalorian descendant becuase he's a clone of Jango (maybe not even understanding it's a creed, not a race), and wanted to become a full mandalorian or something. I'm just spit balling reasons why the clone at the end could be someone other than fett.
as far as "why would mando want to meet fett"? he wouldn't. mando has no use for that. the STORY on the other hand, has some uses for it. it could allow the story to delve into more about what it means to be a mandalorian. does fett consider himself one? if he does, how do his views differ from mando and the culvert mandalorians? we know that there is realistically at least one more mandalorian showing up this season that does not do things the way mando does (at least never did when she was in the cartoons), so is season 2 going to partially revolve around the differences in mandalorian cultures? it may, it may not.
