If there is unnamed header content between named pages it cause extra page break. Workaround is simply to name also header. This is still a bit weird and goes slightly against documentation due you actually "must" apply name to element which is NOT part of normal flow.
"The page property may be applied to any block-level element within a non-floating environment in the normal flow."
Issue is minor / non-ciritical / FYI.
