This is all blatant speculation. It's clearly the tribe from that story, flashback sequences make it clear that the tribe are one in the same and explain how they got there. They are identified as the same people. They have the same names, faces, and memories. All you seem to be leading in you speculation that it secretly isn't them is that the name of the group is off. That is, at most, an irrelevant production error. More likely it's a retcon, as we should treat it.

There's no hidden messages in the comic, if you read it backwards it doesn't read "I am walrus," and the Tribe of Gum were the same tribe was saw in An Unearthly Child. Case closed really.
