I don't think the symbols will end up meaning much more than "hey this is creepy and we want to scare you and we're coming to fuck you up". There could be some meaning to them but they're running out of time to explain it, only 5 episodes left.It makes much more sense for the spirals to have some sort of ritual significance as a former symbol of the children of the forest, than as a message for anyone. Why would you be leaving a message to your enemy behind your own lines where he would never realistically get it, except of course they'll make it back across enemy lines because there are three named characters in that group.
The named characters will make it back to Winterfell, right before they found the zombie kid they said something about how they had horses that could get there faster than the undead.
