You are correct. Actually I think they have to be straight cut for the dog rings to work.
Update looks like I was wrong, there are helical cut dog engagements. Found an interesting article about straight cut vs helical cut gears and the reason whey straight cut are used in race boxes. It's down to the side loads a helical cut gear exerts on the case. Straight cut don't exert any side loads so the gear case doesn't need to be as beefy for the same power level.
