The command: $b is an ordinary branch that happens on the specified line. "$" is the last line of the file. Without a label, "b" branches to the end of the script. So this (being at the start of the script), effectively runs the whole script on all lines _except_ the last line, because at the last line the first thing it does is skip to the end of the script.
