Before getting to the stage where they are head on they should widen their turns when they are opposite each other and re-centre in the converging core. If they don't and are head on they would then need both turn right, effectively flying through the centre of their separate cores and then recentre opposite each other in the converging core.

Sorry to join the debate late.. As Chris says, the two pilots should resolve the potential conflict before it is too late. If they are heading towards each other, the 'break right' rule means that they each have to tighten their turn and risk a spin.

May be, B line Stall? https://youtu.be/-sbuNtjXIx4
No forward speed, but sinking fast?

Thanks Steve! It looks quite a non-event.

In what kind of situation is a B-line stall the best option, and what are the pros and cons of this method of getting down?

If one pilot is higher should they not give way to the lower one?

When landing lower glider has right of way

If one pilot is higher should they not give way to the lower one?

This is a good airmanship question - particularly for paragliders and hang gliders. In most positions the higher pilot usually has a much better view than the lower pilot, and can also judge separation much better - a particular challenge for lower paraglider pilots. So it is good practice for the higher pilot to give extra room to the lower pilot - and remember they might be unsighted.

But in terms of regulations I don't know of any such rule. As Chris says, there's a rule governing simultaneous landings where the lower aircraft is accorded priority, but not in any other circumstances.
