Everything looks like a typical supercell to me. I do see what I think you are referring to though. You can see spiral bands of higher reflectivity in the downshear region of the storm that may initially look like anticyclonic rotation, but they are actually just precipitation particles being blown downwind and are being somewhat diverted by the updraft and rotation of the mesocyclone.
Looking at the southern flank of the storms you may even notice a "backwards" hook. Those aren't backwards either though and there is actually a typical inflow region/hook echo, but it is being impinged on by the RFD surge and it's this surge/gust front resulting in a feature that appears almost like a "mini bow echo". The interface of the inflow region and this outflow region is where the tornado is located. Watching the storm in motion on radar can often help clear some of these things up because there are many times that you'll see very typical processes and features be disguised on radar. Hope that helps! I know what you're seeing but I'm not sure I can explain it as well as I should without going overboard.
