so the difference with mine is just those dash at the start of the
last 2 lines. Is this the same as commenting the lines?
According to the pam.d man page
If the type value from the list above is prepended with a - character the
PAM library will not log to the system log if it is not possible to load
the module because it is missing in the system. This can be useful
especially for modules which are not always installed on the system and
are not required for correct authentication and authorization of the
login session.
So, it isn't the same as commenting the line.
