The unavoidable conclusion, it seems, is that this was an extremely scandalous response from the bishop. (It's clearly confirmed Meg in her erroneous attendance at the Novus Ordo.) But it shows the inherent contradictions in the R&R position.
Either the Novus Ordo is a Catholic rite or it isn't.
If it is, then we are bound to accept it as a legitimate rite of the Church, the Archbishop would have sinned gravely in continuing the SSPX after 1975 in opposition to Rome, and we would all be sinning by attending these Masses rather than at our local parishes.
If it's not a Catholic rite, then the bishop should not have said that it's up to the individual and that we can go there if it's what we feel it nourishes our faith, he should have said we are never to go to it and there are no graces that can be obtained from it. It it's not Catholic, then it cannot have been promulgated by a true pope, because the pope is infallible when he promulgates a liturgical rite to the Church, therefore Paul VI cannot have been a true pope (unless you think he didn't properly promulgate the NO, which I don't think is sustainable).
