I believe they're talking about this feature (https://support.google.com/android/answer/9319337?sjid=18079...).

This is a system you can disable as a user, but it's not the on-modem feature discussed in the article.

How would the modem know your coordinates if the OS doesn't provide them?

It doesn't need to ask the OS, it can just get the coordinates and send them off.
