Open Gate: Investigators may move between any two locations with an attached Open Gate as if the locations were connected.
Safeguard: ...as they move from your location to a connecting location...
Anyone have opinions on whether you can use Safeguard to follow someone through an Open Gate? I'm inclined to think not - the "as if the locations were connected" would only apply to the move action so the locations aren't connected as far as Safeguard is concerned. But I'm also not sure completely sure of the timing - "as they X" doesn't seem to be a defined window but it makes sense that both moves are simultaneous (and this seems to be the consensus), and maybe since it's triggering off the move the "as if" is active for Safeguard as well?
