They did not see Snow and Emma the first time because they were hidden under the ruins.
So yeah, my understanding is that Charming and co. sent the wrath to another world through the hat and it appeared at Philip and co's place and unfortunately Phillip got marked immediately during that fight.
I hope that makes sense
Those two scenes happened simultaneously, but it would have been impossible to show them both occurring at the same time. You would have to use split-screen, Mario Kart style.
