Bear in mind that IBM has been making computers — and terminology — since the 1950s. They invented hard drives. So it seems wrong to say their terminology has “diverged”…from what?
IBM terminals like the 3270 operate almost like a web browser, with form fields implemented by the terminal. The computer sends a page of text, you use the terminal to edit it, and you submit data back. That’s why you have to move around the screen to type things in the right place, and thus why the editor has “line commands”.
