This may help, when you are getting ready to down shift, clutch goes
in, at the same time the gear shift goes into neutral and give it some
rpms with some gas, hence 1 clutch, then push in the clutch again and
at the same time shift into lower gear, thats a double clutch, ask
any truck driver, big trucks do not have syncros, they have to double
clutch.
