I'm asking about why the usage of the mathematics that you and I are apparently both familiar with could be described in different ways depending on which field is referencing it. This is a linguistic question - not a mathematical one.
Nomenclature is different in different fields all the time, or even different areas of the same field. It all depends on what practitioners feel is most intuitive.
No need to call someone rude for not answering your question and asking their own instead.

No need to be rude.
