Sure it will have less stuff, but I suspect there may be some remnants purposefully left behind.
This looks like a basic default apps store uninstall and not much else.
You could argue two potential reasons for this:
1. This script removes only AppX packages. OneDrive is an *.msi package
2. OneDrive is something they reinstall if you remove it, so they really are cramming it down your throat. They wouldn't include it in any debloat script.
