Indeed. This is not corner-grounded delta. Once you figure out open delta, look at dog-leg.
I did some brief reading on open delta and now think that it requires three lines, independent of ground. So I fail to see how open delta would be any benefit save for a simpler transformer (fewer coils) or fewer transformers. It seems as if you would have the same line and insulator cost as more common (closed) delta.
