I think that it is actutally an oversight or an errata. Naturally, if instead the text reflects correctly the intent of the designers, that I agree with you.If they didn't, why would they allow success rather than just tell us that it lasts for 1 minute with no further saves? It seems unlikely to me that they wanted to tell us that, "Here, you get a save that you automatically fail, but if you succeed it ends the effect."
