problem with \noalign

[Tarik Kara]

The \noalign command does not work as expected (as I expect) inside
\eqaling{..}

When I type 

\placeformula[-]
\startformula
\eqalign{
    \forall s_{-i}\in S_{-i} \quad
          & h(s^{\ast}_{i},s_{-i})\pref{R_{i}} h(s_{i}',s_{-i}),\cr
    \noalign{\hbox{and}} %
    \exists s_{-i}\in S_{-i}\quad
         & h(s^{\ast}_{i},s_{-i})\pref{P_{i}}
           h(s_{i}',s_{-i})\enspace.\cr}
\stopformula

the `and` is aligned with \forall. I was expecting to be in the left
margin of the page. Is there a bug (I am using ConTeXt  ver: 2001.7.11) or
am I doing something wrong.

Thanks
