I don't understand the purpose of the 680-ohm resistor connected in // with the first coil. Any idea?

On the 911 618 154 00 relay, the 680 resistor is in parallel with the relay coil.
Pin 86 power is applied thru the diode to relay coil. The 680 resistor is used to dissipate
some of the energy stored in the relay coil, when power is removed from 86.
Info posted in #11 is questionable.
