Yes there are several ways to look at where items are actually positioned on a page or pages of a rendered form. The form model will not tell you the rendered positional elements so you need to use the layout object model. There isnt as much documentation but some of it is described in http://www.adobe.com/go/learn_lc_scriptingReference
To see if an object spans multiple pages, use pageSpan and page methods.
xfa.layout.absPage( <objectref> ) ;
will return the dynamic page number the object starts on and
xfa.layout.absPageSpan( <objectref> ) ;
will return the number of pages the object spans
