Question about online and offline saving. (Dying Light 2: Stay Human)

I went through the prologue offline. I'm standing in the church.
Friend offline completed the prologue. It stands in the church.
He throws me an invitation and we play through the story. All perfectly.
I go to play offline, all the equipment is in place, but the initial save is in the church right after the prologue.
We go online and everything is fine again.
Is it such a feature? Who invited the one and the safe?
