Fun fact: Torx screwdrivers are compatible with Torx Plus screws, but Trox Plus screwdrivers are only compatible with Torx screws that are one size larger
probably because nobody buys anything other than torx, considering it's a brand name, it's not like they're going to just do the funny and mislabel a screw. Phillips heads are so common it's a lot easier to mistake them.
Though if you're in the field and you run across one i could see it being annoying.
