To have LilyPond do something with #(markup ...) you need to explain
to LilyPond _what_ to do with it".

Martin's example embeds it in a music expression. -> Initiate a TextScript-grob

You can store and call it like:
foo = #(markup #:line (#:simple "Second markup"))
\foo
It is called at top level. -> Create top level text

Directly and on top level you could do:
$(markup #:line (#:simple "Second markup"))
Directly evaluate the expression (here at top level). -> Create top level text

HTH,
