Basically, there are 111 different mutations, not 2, and it's misleading to point to a single point mutation and set that as the arbitrary division point between strains while ignoring the other 110 mutations that have been catalogued. There is currently not enough evidence for the researcher's claims that this particular mutation causes observable differences in the virus's reproduction or virulence characteristics that the other mutations do not.
