I'm guessing you are baffled by the === part. This is not Lisp, but meta-lisp
;-) meaning roughly "is equivalent to". So that reads

    (< 0 (length LIST)) is equivalent to LIST

which, of course only has meaning in some contextx (and in some others
it's even false, as has been pointed out in this thread).

I.e., instead of writing

    (if (< 0 (length LIST))
       ...)

you may write

    (if LIST
       ...)

*provided you know LIST is indeed a list* (and not e.g. a string).

Ah, Thien-Thi's conciseness... :-)
