Steve,
Breaker,or circuit is not miss-indentified,circuit(lighting and breaker),is known.Yep,sure your way will work turning off the breakers.
And yes more than likely, is two circuits tied together.But Steve,I'm going to be giving a tugg on every circuit branch wire,including the branch grounded conductors "one at a time", at each terminals anyway. I will be giving a twist with the screwdriver making sure connections landed, are snugg while I'm there looking into this panel.
