"The retrieve-position="first-including-carryover" attribute picks up
the
first matching marker on the current page, or from a section carried
over from a previous page IF THERE IS NO MARKER ON THE CURRENT PAGE. The
retrieve-boundary="page-sequence" attribute sets the boundary for
selecting a previous marker as the current page-sequence, as opposed to
the whole document. That PREVENTS CARRYOVER from the previous chapter."
Also, from a previous post of mine:
"McDonald, Shaun wrote:
"...pagination is done after the transformation, in an independent
step.
Therefore there is no way to get hold of the number of prescriptions
laid out on a certain page in the transformation. The layout
process
itself lacks higher level functionality like counting, so no easy
solution here either."
Is this still true? Is there no way to access nodes by page (for
instance, from a footer template) without forcing page breaks?
That's correct. Some FO processors have extension functions which
might allow [you] to do certain things.

I'm not an expert like these guys, but, in my experience, I was never
able to retrieve two different markers for the same page conventionally.
I had success by wrapping each marker in a filter, then wrapping each
marker's content in a block-container. In my case, I needed a default
footer with variable content, and an overlay footer based on
specifically matched results. Both markers were then absolutely
positioned at the same coordinates. The overlay was given a white fill
color.
That's the how I got two markers output to the same page. If you search
the list for "Shaun.McDonald", I believe you'll find the example. It
should be last on the page. Sorry that I don't have time to apply it to
your situation, but I hope this gives you an idea or two for a solution.

Thanks for the tip, i tried it but it still doen't give me my desired
output.
I change your sample code a bit, i placed the bottom marker inside a
fo:block element to make it valid.
here's a sample fo i'm testing.

a the headers i got where:
page 1: first heading
page 2: second heading
page 3: third heading
page 4: third heading
page 5: fourth heading - fourth heading
but what i need is:
page 1: first heading
page 2: first heading - second heading
page 3: second heading - third heading
page 4: third heading
page 5: third heading - fourth heading
I tried playing with the placement of the markers and the still can't
get the right result. Anymore suggestions?
