Is this just because of mutations after the twins have split? How else could it be possible

  the article talks about this > They measured mutations that occurred during embryonic growth and found that identical twins differed by an average of 5.2 early developmental mutations. In 15% of twins, the number of diverging mutations was higher.

  Expression of genes is also driven by the external environment. Different environment (even minor differences) can result in different phenotypes despite the same genotype. That was the theory proposed as to why identical twins have different fingerprints. Slightly different conditions in the womb result in slightly different fingerprints.
