Don't attach one switch to another switch like that. If the passthrough switch has a fault then everything after it loses power. Standard switches like that should only have one 'hot in' and one 'hot out' in use (this rule doesn't apply to special switches and outlets). Don't ever double up wires on a screw or use the screw and the stab-in connector at the same time. In fact, don't use stab in connectors are all if you can help it. If you ever need to replace the unit you will have to cut the wires off the back. Use pigtails, picture related, anytime you have to 'split' a wire to two different destinations.
