I think it may work, because I had one that did this by accident - it fell from its place weaving up a fence, and it took a long time for me to notice it. By the time I did, it was rooting sideways into the soil, and new leaves formed at the top. It died unfortunately from other causes, but If you had a reason to be concerned and wanted to give it this option, I would think you could do so intentionally, as long as you don't prevent its leaves from getting plenty of air and light in general.
