This is not quite "reorder" but split into two.  It is not yet clear
how it helps, but hopefully we'll find out why splitting the switch
into two switches is a good idea soon in a later step, so the title
needs updating to sell that aspect of the change (unless it is a
pointless change made by mistake that the originally-single switch
got split into two, but that is unlikely the case ;-).
