@shibashecurity it's 100% a typewriter thing, but I don't now remember the specifics. Something to do with the carriage...
Anyway, it's old fashioned and there's literally no reason to do it anymore, but we're only a few generations on from the typewriting days so there are still people writing content who were taught to type by people who in turn had learned on typewriters, so still erroneously teach the old fashioned ways.
