Look closely and see if there is a missing '$' sign in the example.

The -z tests if the string is non-zero in length. "PATTERN" is a
static string and will always be non-zero in length. Therefore the
test for -z "PATTERN" will always be true. You almost certainly
wanted "$PATTERN" there so as to get the "$1" value assigned to it in
the previous line.
