Password Enforcement Pattern -- trailing pattern

This RegEx was posted on a Ruby site as one for enforcing password pattern. I added {8,32} to limit the length of the password, even though I realize no one has passwords longer than that. Rules: at least 1 digit, 1 special character (as defined), 1 upper case and 1 lower case character, between 8 and 32 characters total. The question I have pertains to the trailing .*$ pattern. On the Rubular site, this is required. On regex101.com it does not see to add value to the regex. Do I need the .*$ on the expression?
