Travel from Kastrup to Islands Brygge using Klippekort

We are arriving on a Wednesday, and plan to buy the 120 hour CPH card. I believe it's the new addition this year. But since our arrival day is usually very tiring and much brain fog, we won't begin our 5 day sightseeing until Thursday. Therefore, we will need transport from the airport to Central station, and then a bus to (250S) to islands Brygge. My question is this, if I follow what this blogger wrote, using the Klippekort, do we then use a ticket each for the bus portion? The cheaper option is to buy a klip kort. Since you need to travel 3 zones into Copenhagen, you can get a 3-zone klip kort, which entitles you to 10 trips over 3 zones. But depending on how much traveling you plan on doing, I suggest that(for a couple traveling together)you get a 2-zone klip kort. Since there are 2 people traveling and you are both traveling through 3 zones, you will need 3 klips on a 2-zone card. 3 x 2 = 6 zones. A 2-zone klip kort is 130 kroner, so you pay 39 kroner for 2 people versus 63 kroner. You will need 3 klips to get back to the airport when you leave, which will be another 3 klips. So your trip back and forth to the airport for 2 people is 78 kroner versus 126 kroner, plus you still have 4 klips to use while you are in town. So you can take another trip together in a 2-zone area, which is plenty for traveling around Copenhagen.
