Totally makes sense.

Or/and... You do not want any
power going to starter solenoid(relay 3)coil unless shifter is in N..
so you don't want Relay 2 coil operated & passing
power thru it's contacts to the coil of Relay3...
so you insert a momentary switch in shift mechanism. It only closes it's contact & passes power to relay 2 coil,when momentary switch is mechanically activated in the N position.
Shift to N & turn key to start position. The momentary switch is "turned on" by a cam at N.
Power from the key turned to start position passes thru the now closed contacts of the momentary switch and reaches the coil of Relay 2.
Relay 2 operates & passes (probably Hvy duty) power thru it's contacts to the coil of Relay 3.
Remember-relays have a coil that requires power. They also have contact(s).
Operating the Relay closes Normally Open (N.O.) contacts & opens Normally Closed (N.C.) contacts.
Very usEful buggers! Hope this helps
