I'm no expert skeldol ... 3.5 year beginner ... I don't think it matters if the tip of the index finger is above the neck. I think all that matters is that your finger is aligned so that the notes fretted with the barring finger are all clean.
Does look like the index and middle fingers are fretting on the fretwire, rather than positioned behind as close as possible, like the pinky but that may be camera angle ...
