Maybe it will be easier to understand if you try:

$ git help help

or

$ git help --help

or

$ man git-help

:-)

Yeah, it is one of the reasons.
There are systems where "man" is not the standard ways to get help,
and text on the command line is not the prefered format for help
content.
So the "git help" command has different default depending on the OS to
better suit user expectations on each OS.
This way people can just be teached to use "git help" and that will do
something sensible everywhere.

Yeah, so we need that to work to make people happy on unix systems.

Another reason is that "git help" provides more configurability and
more features like its -a and -g options.
It could provide even more in the future, like options to search in
the documentation.
