does autoload do anything?

[Sheldon]

Hi

I've done some digging and testing around the autoload feature (http://
code.google.com/apis/ajax/documentation/#AutoLoading) of google.load()
It seems from the documentation initially that it would append all the
intended js files into 1 request so that you only have 1 server round
trip, no matter how many you request. This doesn't seem to be the case
during my testing however, as I still get 1 round trip for each file
being requested.

What exactly does the autoload feature do to benefit speed? Seems to
me I get the exact same number of server round trips using auto load
or not using it.
