You just proved my point, it doesn't (see below) ;-)

Because of the subject of this topic - getElementsByTagName fails (at
least on Gecko) while document is loading. Run my test on Gecko and you
will see lots of red labels (errors). Please view source :)

Wrong, as this means scripts have paths relative to the current
_document_ (vs current _script_).
e.g.: Page "/myapp/index.html" includes a "js/load.js". Using your
simplification...

^ absolute path would be "/myapp/foo.js", which obviously is incorrect,
as "myapp" modules are stored in "/myapp/js/".
Anyway, that loader is just a lazy example, to prove that it can load
correctly even scriptaculous (with is own buggy loading procedure).
Obviously, it can be improved to support even more complex paths, like
"../lib/", etc.
