That's what it is now, but my understanding is that originally "snap" was defined as the difference between those throwing Teebirds 350' and 450'. Not nearly as much was really understood about what went into "snap" so a single, generic term was used. Now there are many more terms that are more descriptive and specific and people use "snap" to mean a bunch of different things, many of which have nothing to do with the original definition.
I like to describe OAT in aviation terms roll, pitch and yaw. Yaw is "on-axis" torque, and also what we call "spin." Pitch is nose angle and we rarely talk about this type of OAT, but it does exist. Roll is the "off-axis" we're normally talking about.
