Starter solenoid wiring

[Breadstick]

I'm replacing all the wiring in my 72 C20 with a painless performance wiring kit. When I was wiring the starter last night, I noticed the two smaller lugs on the starter solenoid were jumpered together. Is this normal? The painless kit only has the purple wire going to the starter solenoid start terminal and I've not seen this jumper on a starter before, but the truck started and ran fine when it was wired this way.

I still have a way to go before I'm ready to power on and test the system, so hopefully this won't be an issue.
