defined behaviour for multiple urls for a remote

Hi,

What's the defined behaviour if I do this:

[remote "both"]
	url = https://code.google.com/p/gitolite/
        url = git@github.com:sitaramc/gitolite.git

I know what I'm seeing (a fetch only goes to the first URL, and does a HEAD->FETCH_HEAD because I didn't provide a refspec line, while a push seems to push all to both), but I was curious what the official position is, because I couldn't find it in the docs.
