That looks absolutely bizarre.
For multi-gear bikes, off-center rims are common, generally with all of the spokes going to the left (non-drive side) of the rim, and thus improving the spoke angle on the drive side.
Yours has the IGH, so less dishing needed, but the offset is opposite from what would normally be expected.
It is easy enough to check the wheel dishing with a dishing tool (your LBS should have one).
You cold shove a rod or something through the spokes to compare right and left centering of the hub.
I would think you would get a stronger wheel with a normal cross pattern, or I have wondered about crossing the right flange to the left side of the rim, and visa-versa.
