There is a gadget in flowables.py that attempts this sort of thing. It's called 
PTOContainer and attempts to do injection of specified lists into the flow when 
it is split. (PTO stands for "Please Turn Over"). Personally I hate it as it's 
full of edge cases and bugs. For your case I guess you need to do something like

story.append(PTOContainer([section1flowables],header=[ContinuedSection1Flowables])

give it a whirl and see what happens.
