The rule has good intent, but this is one of them rules we really don't need and that could cause problems for some unlucky smuck in the future. I know, I have been a smuck before.
The 6" offset rule should handle most problems in this area. Years ago we had a guy that attached a stub shaft to his counter sprocket with a double row chain flex coupler, then he welded a bearing carrier to his frame rail and moved both sprockets outside the frame rail to make gear changing easier. That was before we came along with the radical left offset like used on midgets which made that idea a non starter, now we rub the left rear torsion arm with the left rear tire sidewall and don't have anyplace to put the sprocket but inside the frame rail.
Looks like that rear sprocket and chain is outside the left rear lower frame rail to me on the attached pic.
I got this kid that works for me who is showing me all kinds of neat things to do on a computer. Now if I could only remember how to do them by myself.
