When this was reported there the other week (through some summary article), it was unclear to me. I was looking, because my first thought was that if it's actually skipping that space, and if it's instantaneous, isn't that FTL communication? You could encode information in magnetic fluctuations.

Indeed. The light speed limit is only valid when moving through space. If you bypass it, nothing actually stops it from having FTL (Faster Than Light) communications/travel.
To understand wormholes or portals from the Valve game, you can think of our 3D universe as a 2D sheet of paper. You cannot move along the sheet of paper faster than light; however, if you bend the piece of paper, you can make it so that two different points on the sheet touch.
A wormhole is just this pair of points, and finding a way to switch between the two connected pieces of paper. Since those two points are actually in the same location, traveling from one to another should be instantaneous.
