I see this "%@{@code{..." markup appears in the paragraph just before
this, but it's wrong. The whole thing needs to be wrapped in @samp and
the nested @codes removed, like
s/%@{@code{S}:@code{X}@}/@samp{%@{S:X@}}/
etc.
I also suggest using the present tense here instead of the subjunctive...
s/would substitute/substitutes/
s/were given/is given/
