This is explained in the help files, with examples.
Really.
Now I agree that it's a peculiar way for it to work, but
it is in fact doing exactly what it is documented to do.

Someone long ago decided that  "using 1:2" should
behave differently than "using ($1):($2)". I don't know
why, but we're stuck with it unless we want to break 
with all previous versions.
