See p.140 of the 'PDF Reference, version 1.7'.

If I remember it right the pdftex macro for writing those entries is 
\pdfcatalog. Maybe interferes with the automatically created entries!?

In ConTeXt you can use (tested) the non public macro

\doPDFaddtocatalog{/PageLayout /TwoPageRight}

You should also add a feature request at the ConTeXt mailing list for 
that. It looks like the 'TwoPage*' variants are not officially supported 
yet (couldn't find the keywords). I want them too :D

Best wishes,
