I really don't think this is entirely spurious considering Elon has been using LLMs to fire government employees. It seems like a very plausible explanation for how they came up with this policy.
from Mike Johnson, about DOGE's use of algorithms: ""Elon has cracked the code. He is now inside the agencies. He’s created these algorithms that are constantly crawling through the data. And as he told me in his office, the data doesn’t lie. We’re going to be able to get the information."
My speculation, but it's very likely that one of those pieces of analyzed information was the 5 bullet points from each federal employee justifying their job.
