I think this confusion occurs because when heading west you arrive at the eastern field boundary and vice versa.
My teaching was always to set the bug on the DI / Compass whenever possible as a reminder. As in FREDA rejoin checks, where D = DI / Compass. I do this as matter of course, although I've been flying for 25 yrs or so.
ATC can help out by allowing a rotary wing to join via the standard FW circuit pattern if possible, especially if the pilot isn't used to the local heli procedures (which tend to be different at almost every airfield). Everyone should then know where to look for the heli if standard RT is used.
