unique.

myip is at the mercy of the interception lookups.

myportname only depends on what you put in squid.conf and which actual
listening port the traffic arrives on.

The ACL values can of course list several port name= values if you want
several ports grouped to be handled the same.

The only subtle problem I have been able to think of is that wildcard
listening ports are neutral/agnostic of the packets arriving on them.
  The name is fixed with the actual receiving port on Squid, not the
client visible IP.
  This is by design, but can be confusing to some who don't realize how
wildcard ports work. Particularly when dealing with multiple IPs spread
over multiple protocols.
