Perltidy reads a Perl script and writes an indented, reformatted
script. The default formatting closely follows the recommendations
in perlstyle(1).  Perltidy can also display perl code in syntax-
colored HTML output.

If you want your code to conform to style.perl(7), you should use:
perltidy -i=8 -t -pt=2 -bt=2 -sbt=2 -ci=4 -noll -sfs -nasc -ce
