This seems to be a particularly extreme case of unconventional terminology usage, but on the whole, the phenomenon you describe is the inevitable consequence of trying to be concise while also not inventing words. The information density of the existing language just can’t handle the depth of all the fields we try to use it for without inventing terminology. Off the top of my head, I would claim that any large subfield of mathematics is probably as bad, if not worse, than software development (see: all the words used to describe “a collection of things”). I would expect this to be true for any sufficiently developed field of study.
