It could equally be argued the cyclists were not creating the tailback, the convoy of vehicles coming the other way was preventing overtaking and causing the tailback, and the convoy of vehicles behind were contributing to the tailback.
Cycling two abreast may have been the best decision. If they had singled out, motorists likely would have tried to squeeze past, putting the cyclists in danger. When it comes to overtaking which puts all the risk on the cyclist, the cyclist has every right to discourage it until they deem it safe for them. This is necessary until motorists are all able to judge 100% of the time when it is safe to overtake a vulnerable road user.
My safety trumps your convenience.
