In my experience as a radio operator (non Aviation industry) I would agree that clear comms are vital to success. As soon as any level of ambiguity creeps in, one can find all sorts of things going awry, usually in a dangerous manner!
So, whilst I don't have training in ATC ground comms procedures, I'd say: "Yes, you do have a good point.
" Presumably these things are fairly standardised are they not though?
