Can I bleed brakes old fashion way?

Toyota mechanic buddy told me doing it the old fashioned way is a surefire way of springing new leaks on old brake lines, you can bleed the brakes by simply opening/closing the driver door which activates the pump for a short period. Has anyone else heard this rumour?

 

Having someone push the brake pedal is much more reliable. Which you do while you're in "invalid mode", which is explained very clearly in the aforementioned, linked, and recommended @NutzAboutBolts video. I'm losing interest in this, though

 

Do not ask your Toyota mechanic buddy to work on your car!!! What he told you is wrong. Activating the brake pump by opening the drivers door does NOT bleed the brakes. Please provide the name of the dealership that he works at so that other people can avoid that dealership. I would not let that mechanic touch my car.
