They're not "breakthrough" cases since the vaccine was never intended to stop transmission and very clearly does not stop transmission. They're just cases amongst people who took the vaccine.

And their definition of unvaccinated includes partially vaccinated (1-shot) and probably includes recovered individuals. See table 2 for their results which finds that boosters do significantly reduce transmissibility and susceptibility, but it is just very far from the perfect effect everyone would have hoped and wished for. Vaccines are probably still more effective than masking in preventing transmission (given the average person's adherence to masking guidelines) and the effect would intuitively (to me anyway) seem likely to stack.
