I realize that common names vary as they are "common" names.
And I believe the video was referring to a certain member of the mayfly family, and calling it by a "common" name rather than its specific scientific name.
No, he's saying that in the British Isles, "mayfly" only refers to one species, which is very similar to the Green Drake (Eastern) in this country. The term "upwing" is used to refer to the order that we here in the US call mayflies. A mayfly is an upwing; just a specific one. (There's a reason that entomologists use Latin.)

There's no difference in the scientific classification.
