This seems to confuse git with GitHub

Yeap. At no point git matters. It just checks releases from specific site (for now only GitHub but checking code other forges are considered) and downloads. Basically a simple package manager that only does fetching (and guess that's why it is named binary manager).

It's not git based. It's HTTP-based.

My bad, thanks for pointing this out
