So, just a hunch that it would be a company name or something else that might be in the dump? There's no technical reason for the actual password itself to somehow end up there? A serious security flaw or something?

What I mean is, we are reading about it because it worked.

It's the lowest hanging fruit. I doubt he expected to find the password just sitting there, but since he did, here we are :)

But yes, keeping sensitive information hidden in plain text considered a security flaw.
