Critical engine on jets is the upwind/outboard one. Have less rudder power available losing the downwind one, since some rudder is allocated to counter the crosswind as you said. Would have to give more thought to props with P factor, counter vs. co-rotating, which side, geometry in relation to prop wash effects on the vertical stabilizer, lose of lift on the upwind vs. the downwind wing if engine quit at rotation, ... Would still think upwind engine loss would be critical for prop twins, unless he's talking about losing powered lift at rotation.
Engine out crosswind landings would be a non-event unless you allow for go-around after touchdown. Then the takeoff case applies.
