Not sure how that doesn't mean 'didn't have a beginning'.
I don't know what Jehanne means exactly here, but you could theoretically have a 4D space-time continuum that is infinite in its dimensions but nevertheless has a "starting point" (i.e., the BB singularity) contained within it (sort of like the origin point of a coordinate system). In other words, the universe (by universe, I mean the whole space-time continuum here) has a beginning in one sense (has a 'starting point') but no beginning in another sense (has always existed).
I agree, however, it doesn't mean there's a third possibility here. It's still either the universe has a beginning or it doesn't (regardless of how "beginning" or "time" or whatever are being defined here).
