When, not If lava crosses 130...

At this point I don't see any need to jump the gun and alter anything with regard to the current flow and I would consider it counter productive at this time. Every time one of these flows occurs to the North and then stops, it increases the elevation to the North of the vent bringing it ever closer to the elevation of the rift in that region. It could potentially create a natural barrier to the north that guides everything to the south of the rift if left alone.
