I think the guy you quoted spelled "delusion" wrong.
The hips are wider (left to right) than they are deep (back to front), so when you rotate back the hips will appear to move back unless you prevent that by keeping the hips forward. Then when you swing down the hips do rotate similar to where they were at address, so from a face on view some of the forward movement can be attributed to counter-rotation, but the at impact and beyond the hips should be in front of where they were at impact.
If you want proof, look no further than Tiger Woods (or literally any other PGA TOUR player). If you look at a video of Tiger, the place where his left hip was at address is about where his belt buckle is at impact.
