It's interesting and informative how different people see different things in the same pictures. Especially Stush's comments about the health of the plant. If I might weigh in on the subject...
Restarting the terminal rosette from a cutting is the best solution, and best delayed until spring. But two things to consider above and beyond that.
One, I agree with Thijs that the form of the plant may just reflect how it naturally wants to grow. In other words, cutting and restarting will only delay the resumption of a stemmy sideways growing form. The stem is not necessarily a problem in its own right.
As for the health of the plant, it's not looking great. Maybe the roots aren't working right or the plant is tired of being in the same container with the same soil for so long. In my own container garden, I am constantly on the lookout for plants that are looking marginal, buggy, losing life force, or hopelessly constrained by the size of their container. By constantly weeding them out (or taking action to reverse the course) I think the garden improves in vigor over time. It's not like there aren't plenty of baby plants sprouting all over the place here.
Anyway, if that was my plant, I'd just chuck it and move on unless the flower was particularly good. I realize that wasn't the question, just sharing my point of view.
