Its situated no differently than where QF have them installed and other airlines. There's a bit of space there and it's pretty much where the old bulkhead divider was.But is the end bottom of divider over the edge of the J seat or in fact a little more into row 3, that would make the difference in the ability "I'll use that word intentionally" to hit your head against the bottom of the divider.
Taking into account the curve of ones head and that your head motion would have to be lifting directly from below the divider, seems an awkward non practical situation.
Idiots will always be idiots.
