Form 709: Gift splitting confuses me

The wife and I gave a large enough gift in 2019 to require Form 709. We are in CA, a community property state.

 

Form 709 instructions say we must each file a form for half the total gift because it was community property. That part I understand.

 

What I don't understand is the term "gift splitting" and the split gift part of 709. I am guessing that "gift splitting" does not apply and I should leave it blank because we're each filing for half the total gift. Right?
