Town planning and cycling a.k.a bad junctions

Sorry, just to be clear, I'm not talking about the junction, I don't RLJ into oncoming traffic, it's just a filter. I could get off, on to the pavement, walk a few metres and remount I suppose, but that wouldn't give me that extra time to get ahead of the traffic up to the top of camden town.

this is where I mean - https://maps.google.com/maps?q=camden+town&hl=en&ll=51.534934,-0.138826&spn=0.0012,0.00327&sll=37.0625,-95.677068&sspn=49.624204,107.138672&hnear=Camden+Town,+London,+United+Kingdom&t=m&z=19&layer=c&cbll=51.534982,-0.13886&panoid=6jVxlxOccet375jG0fisOw&cbp=12,328.83,,0,6.42

When the lights turn green on that right hand lane, is there already traffic moving in the left?

If so, yeah that's not going to be much fun to negotiate on a bicycle, even more so if you're a slow and/or not a very confident cyclist.
