LGTM, but I am also not well-versed in vector operations, so you may want to wait a day or two for @uweigand or someone else to sign off as well.

Because the two methods do considerably different checking, and I would have expected there to be more behavioral differences in the tests by removing the call to `CheckVectorOperands` that suggests there are tests missing.
