That's what I was taught, but our (within NGA) grasp of Japanese terminology is tenuous, for the most part. We have no real link back to Japan to make it necessary to use the terms correctly, so we probably bastardize on a regular basis.We use uke and tori universally. Some styles (Yoshinkan) also use aite and sh'te.
I believe that "nage" could well mean "the one that throws" but I'm not sure that there's this kind of semantic link between tori and locks.
