The headings are given for a variety of reasons as the Wobun (and Buzad) deps out of Heathrow conflict with a shed load of traffic. You've got the inbounds to Heathrow, Stansted, City, Luton and Northolt which you are trying to climb against for a start. Then of course you've got the outbounds from said airfields to contend with. The NW Deps controller also tries to attempt to put the outbounds the correct way round for the Midlands controller i.e. a/c routing via TNT to the west of those via POL. Also the NW controller is trying to position the outbounds in such a way as to give the Midlands controller a fighting chance of getting these a/c through the Brum, Cov and E.Mids inbounds.
As always better explained when at the coal face so to speak and the south coast is actually quite nice.
