And as has also been asked - why do they symlink to the /usr/bin directory in the first place then?
They have three perfectly reasonable directories they can install into, which is what they recommend that application developers do when installing their software:
/Applications
/Library
/usr/local
So why do they feel the need to link git into /usr/bin? They could link it into /usr/local/bin - the $PATH variable includes this directory already.
You state that plenty of comments explain where the Xcode git actually is, but that misses the point entirely. Why is it linked into /usr/bin?
There are no symlinks in /usr/bin, they are wrapper programs determining whether you already have the Command Line Tools or full Xcode installed. If not, they will open dialogs asking you to install these additional software packages.
