Not true. The hoist is the hoist, the tack is already out when you have a separate tackline. For single handing its the only way to go as you are spending less time either not steering, or pushing the tiller extension around with your legs when you are getting the kite up. Yes you pull the same amount of line, but you can get the tack out while you or the crew is still on the wire, which means more time at full speed.
