If you're talking to average people, yes, your way of wording it would be more efficient.
However in certain domains accuracy is key, so one tries to communicate with as much detail as possible. In order to achieve this without being hyper-verbose, one uses an established set of vocabulary, whose subtle and detailed meaning is well-understood and common in that industry. That may make it sound strange to outsiders, but minimizes the risk for misunderstandings and lack of clarity amongst peers.
