He's had the Niederlassungserlaubnis (permanent residence permit) for 3 years already so I assume he must have had an ordinary residence permit for 5 years to get that.
You can hold the permanent residence card and the Erlaubnis zum Daueraufenthalt-EU (Permanent Residence-EU) card simultaneously, just need to have had any any residence card for 5 years, know about Germany, speak some German, etc as a prerequisite.
If you stay outside the EU for more than 12 consecutive months, you can lose the Erlaubnis zum Daueraufenthalt-EU and residing outside Germany for 6 years or more can lose it too.
