Makes sense to me. With no ghost runner, Langeliers should never have reached, because there'd have been zero reason not to go straight to first on his ground ball.
Like @SteveA said, the rules tell the scorer to reconstruct the inning without errors. As "no error shall be charged to the opposing team or to any player," when you reconstruct, you don't include the ghost runner, because he was placed, and he didn't reach base as the result of a play (as in, no error was changed to the defensive team or any defensive player).
