Double cousins

Double Cousins: When two siblings in one family marry two siblings from another family and each couple has a child. These are called double cousins because the children share the same sets of grandparents. ... Twice removed means that there is a two-generation difference between cousins.Dec 23, 2018

But they are more than that. Identical twins have the same dna. Since all 4 parents only have the DNA of just 2 people, genetically these two kids are siblings.

Yeah, the situation is different because the parents are each identical twins. Just like what @Sterling Archer said.
