I was confused by the source code, the variable that keeps track of this is called "am_root", which implies that rsync has taken some action to determine whether or not it is running as root.

What the variable really means is "should_root", and the source of this variable are default operation and the settings --fake-super and --super.

The confusion I faced was that permissions stored in --fake-super were overwritten by the permissions used in the target directory, in the process the source permissions were lost.

I have submitted a patch to fix this here:
