This is an inaccurate statement. Geocentrism makes identical predictions to heliocentrism, but clearly the two models offer differing explanations of the dynamics of the solar system.
From an engineering perspective, yes, predictions are all that you care about. From a scientific perspective, the end goal is the simplest and most general set of explanations possible.
