I think that the wire is to help keep the upper wing from tipping up and down slightly. Maybe with the slanted strut, the connection for the strut is not able to carry moments. If that is the case, in principle, there should be two wires per side. One from bottom of fuse to upper wing, and one from the lower wing to the upper wing. You could use a single wire per side, but that means that under certain conditions, only one wire is carrying load (when subjected to tension).
PD. Just looked at the photos on their website and the struts appear to be pinned, therefore, they cannot carry moments and hence the wires...
