Yes, h:panelGrid looks at it's lays out each of it's children according to columns attribute. Simply, ui:decorate add's all of its children directly to it's parent BUT s:decorate is a component in it's own right, so keeps it's children. There is nothing we can do about this, and keep the span AFAICS. Anyway, using a panelGrid with s:decorate isn't very useful IMO.
