Previously, when you had the bar behind mid-foot, this didn't shift the bar forward of midfoot because you were so far behind. But now that you're in a better position on the way down, you need to stay tight to KEEP this position, instead of letting it go by being loose and shifting forward.
So I'll repeat part of my advice from your OP: Stay Tighter! Slow and tight on the way down. But initiate the movement with knees and hips together, then once you're about halfway down, knees only go out and hips continue to go down/back.
The only way to get a better kinesthetic sense of staying tight and depth is to keep doing it, while being cognizant of those things. Keep plugging away, it will improve.
