Sure, but three is a far cry from 50-150, which would almost certainly be reported as a rearrangement or some other sort of structural variation, and would be detected with an entirely different method than SNPs. Alternately, they're talking about their sequencing reads and calling them SNPs. I think I should just chalk this one up to my own personal Gell-Mann amnesia and let the article authors do their thing.
