Obtainium warning re difference btw app sources and package source

Elgoog

When installing the VLC media player app with Obtainium, I see the following warning message:

The app source is 'get.videolan.org' but the release package comes from 'ftp.halifax.rwth-aachen.de'. Continue?

AppVerifier says the APK is good.

Is it OK to install?

That seems to be a Mirrorserver which hosted VideoLAN's Download-repository. It belongs to a well known public university of technology in Germany (https://www.rwth-aachen.de), so it should be fine especially if AppVerifier says, it's fine. They are also hosting repository mirrors of some Linux-distributions and some other stuff.
