Urs is being somewhat pedantic.  push copies your changes to the server. 
There's a difference between what I just said and what you said.  Since git 
is a revision control system, it really works on the basis of changes in 
revisions, rather than uploading files.  However, with files where it can't 
track change (i.e. binary files), the only change it knows about is that 
there's a completely new version of the file.  Therefore the whole of the 
file gets pushed to the server, so in ftp terms, it would be uploaded.

It's easier to consider this in the context of text files, where if you 
change a single line, all that is pushed to github is a message saying 
"hey - there's a new line 4 - here it is".

See above.

If you _want_ to work out why Urs believes this, then 
http://lilypondblog.org/2014/01/why-use-version-control-for-engraving-scores/ 
may be of help.  Otherwise, stick with my recipe for now.
