You need some play at the Master Cylinder Pushrod to be sure Master Cylinder Piston returns to end of Cylinder when Clutch is released.
The Clutch and Brake Pedals don't need to be at same height unless you left foot brake

Of course! It's the blocker rings in the box which prevent engagement when the shafts are rotating, one forgets these things.
