No, failat sets the level at which the script will halt and not continue.
So with FailAt 21 it means that any error below 21 will not halt the whole startup-sequence, it will just fail at that line and go on. I don't think they did it to expect something failing, rather to make the startup-sequence work through even if something you add fails.

>NIL: redirects anything the command outputs to the null device. This is so nothing is shown on a shell window. It's useful in the beginning of the startup-sequence, because it will not open a Shell window until there's some output. There could be tiny memory implications on this (opening a screen with a Shell window uses memory) but mostly, it will mean your boot will go almost directly to WB without showing a Shell window (unless other stuff throws output).
It also cleans up the startup, otherwise everything would be verbose.
