Kill cord / dead man / on the larger boats?

Its on Mercury throttle controls. The manual says so you can stop the engine without taking your hand off the controls but why would you need to keep your hand on the throttle when switching off?
Just thought of a reason; if the key is in the wheelhouse control panel and you are up on the fly
 
It is relatively simple for some one like Dougal Tolan or Mike Fleetwood on here to rig a Raymarine lifetag to make it stop your engine if you go out of range, or make you a similar device from scratch. You wear a pod which has to be within a set range of base. There has to be a cancel button for anyone remaining on the boat to restart and pick you up, also an activate button on the pod in case you want to stop but are still within range.
I had this idea in 2005. When the RNLI trialled the CPRS confidential position reporting system on my boat, and also proposed their Mobguardian originally it was active, i.e. you had to activate it for it to work. I pointed out that you could have a passive system that works on signal failure and that's what they did. I suspect that's where Raymarine got the idea for Lifetag.
The CPRS sent an alarm in the event of the boat electrical system going dead. Unfortunately when crew slung a pot against the wheelhouse front the consumer unit inside spat out the neg from the busbar, and I had to hurriedly phone the cg as I couldn't find the fault quickly.
