That is logical, and reasonable, but ...I also recall that electrical sockets were referred to as "plug sockets" ( sockets for plugs ) as they were not sockets for use on nuts and bolts.
... is neither logical nor reasonable. That would be like ('lazily') shortening 'pipe socket' to 'pipe', or 'eye socket' to 'eye' - either of which would be pretty ridiculous... And maybe lazy speakers dropped the socket and just said "plug" when referring to a socket.
