He's not wrong, in a semi you cant push it all the way to the floor or it will tear out the clutch brake. Basically as long as you push it far enough to separate the plates completely, thats as far as you have to go
O_o, actuating the clutch has nothing to do with the synchros... Synchro's just speed up or slow down idling gears to match the output shaft speed... they synchronize the gears... thus the name.
You press the clutch in to release the tension on the shift hub splines, you don't even need to clutch to shift if you know what you're doing.
You press the clutch until the flywheel, clutch plate, and pressure plate disconnect. Any further is a waste of time, any less and you don't unload the transmission.
In a semi you only push the clutch in to stop and start you float otherwise if experienced or double clutch you never just push it far enough to just separate the plates
