It seems to me that the football family tickets are issued randomly in the so called home ends. From my seat the Stadium looked to be split 50/50 with the middle ring for Club Wembley. So if you factor in 23000 tickets were given to the football family you can see why opposition fans could be in home ends. Seems stupid to not just have the middle of the upper and lower tiers for these tickets. Bound to be issues when goals are scored and so on!
