I tried to understand the significance of this (parent maybe implied that they reused a completely fictitious identity generated by some test code), and I think this is benign.
That project just includes some metadata about a bunch of sample projects, and it links directly to a mirror of the xz project itself:
I assume it downloads the project, examines the git history, and the test then ensures that the correct author name and email addresses are recognized.
(that said, I haven't checked the rest of the project, so I don't know if the code from xz is then subsequently built, and or if this other project could use that in an unsafe manner)
