yeah, that's one of those UI busywork fails, but that's also a workaround to lag

With a pie menu you could have it activate if you move your mouse far enough from the center (so that there is no way to do so in a wrong sector because the sector area is at that distance is large enough to make it easy to avoid such errors), so no clicks and less precision required
