I suppose I should start by recommending that each column be shipped out 
as a page, if it is indeed a page, and let the DVI program handle it.

Or I should ask why a column is "left hand page" with its own page number.

But I will give some practical recommendations instead.

I expect the page numbers are being written to files for cross referencing
and compiling a table of contents.  There is no reason, then, why the explicit
page number need be written to the file.  The thing to write would be
\ifleftcol 13\else 14\fi, where \ifleftcol is set true or false by
writing \leftcoltrue at the top of the left column, and writing
\leftcolfalse at the top of the right column.  Thus, a TOC file
would look like

\leftcoltrue
\TOCentry{section}{1}{Introduction}{\ifleftcol 1\else 2\fi}
\leftcolfalse
\leftcoltrue
\leftcolfalse
\leftcoltrue
\TOCentry{section}{2}{Theory}{\ifleftcol 5\else 6\fi}
\leftcolfalse
\TOCentry{section}{3}{Procedure}{\ifleftcol 5\else 6\fi}
\leftcoltrue
\leftcolfalse

Cross referencing is done similarly, but the cross reference macro
has to be \edef-ed to evaluate the \if.
