Because, as you say, the ${lookup will return '0' or '1' - so it can
be used directly as the "then" value of the ${if.

Right, so follow that line of thought. If the {${lookup... in
Jacob's syntax isn't be a parameter of the 'eq', the syntax rules say
it must be whatever comes next - the {then_string} parameter of the
${if.
