I suspect the modifier \key is mucking things up somehow.  Eplain
provides special mechanisms for inserting font changes etc., which
indicates to me that the insertion of tex code directly into an index
term  doesn't play nicely.

I don't think you can mix \sidxmarked and [seealso]. I know you 
can't mix [seealso] with [pagemarkup]. So you
will need to something creative on the output side, such as hand
editing the foo.ind file or modifiying the \item and \subitem macros.
