That’s word games.

If I launch 2 network requests from my async JavaScript and both are in flight then that’s concurrent.

Definition from Oxford Dictionary adjective 1. existing, happening, or done at the same time. "there are three concurrent art fairs around the city"

It is an attempt to delineate some classes of concurrent & parallel programming challenges using a new term (really, redefining it in the programming context to be a bit tighter).

Oxford dictionary holds no relevance here, unless it has took over a definition from the field already (eg. look up "file": I am guessing it will have a computer file defined there) — but as it lags by default, it can't have specific definitions being offered.
