The Vr. fenestralis that I have bloomed last summer. It has produced 4 pups for me so far in the manner typical of Vr. fenestralis- midway between the inflorescence and the outermost leaves. That means mangling the mother plant when removing the offshoots. If it makes you feel any better, the flower spike isn't all that special. Bracts are marked like the leaves, though the flowers are kind of pretty. Almost like a pale yellow gladiolus!
I think that our Michigan winters (6-8 weeks with very little sun, and cool temps) trigger certain plants into flowering a bit precociously. I would probably envy that your specimen is likely far larger than I would be able to grow here! Paul

I second everything bromeliaddict has said. Be glad it hasn't bloomed or pupped, because a big full foliage specimen is much prettier than a smaller one with a flower, and the pups are among the most difficult to remove of any bromeliad. You can't do it without messing up the mother.

Vr. fenestralis grows very large in the tropics , have seen small plants in flower in sub-tropical Brisbane .
Here a plant would be nearly 1m or 3' across before it flowers .
