I highly doubt this (though I never look at one long enough to see it
"changing" its working leg).

Maybe they are just conserving a habit :-)

By the way, it's really entertaining seeing them hopping for tens of meters
instead of getting their "resting" leg out in the cold.
I always asked myself if the overall energy balance was interesting: it seems
to me (maybe I'm completely wrong here) that it would cost less energy to
walk ten meters and then put the leg to rest again. But I probably don't
think like a Dunlin ...

A bird in the bush is better than two in the hand.
