Ludisia discolor: propagating from leafless-stem?

[tropterrarium]

I have just repotted/re-configured an exuberant Ludisia discolor. The various branches readily snap off at the junction to the next piece of stem. Stick that in dirt, and it will grow roots. Have done that before, works like a charm.

After snapping off all the terminal branches with leaves on them, I was left with one leaf-less portion of stem, about 8 inches long. I stuck it in the pot anyway, but am wondering whether this is an exercise in futility. Anybody having experience with that?
