Yes. First, those young branches will have to grow out and make new
leafy plants similar to your existing plant.

They may grow out as a short or long rooting stem before
making a new leafy plant, or they may form a denser
clump apparently from a common base.

In nature bromeliads sometimes form large clumps of leafy
rosettes connected by these creeping rooting rhizomes.

I think, they did quite well:

Contrary to what they suggest, you can also simply choose to leave
the offsets attached to the original plant. They'll grow faster
living off of the "mother" plant than if they're cut off too soon.
When the new shoots get big enough they will flower and make new
leafy branches of their own.

When the clump of plants gets too large you can divide it into
smaller clumps or into single plants, discarding the old parts
that have already flowered.

OK, so how do I divide the plant? Do I just cut the purple parts as
low as possible? And what to do next? Just put them into another pot
of soil? Or do I put it into a glass of water?

Would be very sad, if i killed the new offsets by treating them
incorrectly.

Thanx for further advice!
