I tend switch out which hand I use when my muscles get tired, but I’m still left-handed. My hypothesis is that if you’re not actually ambidextrous, that habit is more likely to develop in lefties because you are generally forced to use you right hand for certain tasks, making your right hand more coordinated than righties’ left hands. That causes your right hand to be more readily available to fill in for your left.
