LJ dependencies

I don't yet quite understand how those dependencies at the end of the BML pages work (and what they're for at all), but isn't something missing here? This is from talkread.bml:

link: htdocs/talkpost.bml, htdocs/talkread.bml, htdocs/delcomment.bml
img: htdocs/img/dot.gif, htdocs/img/delcomment.gif

It's missing the link to htdocs/talkscreen.bml and the imgs img/btn_del.gif, img/btn_scr.gif and img/btn_unscr.gif.
