so once you cut the top off, do new shoots come out of the side? How would you get more stems then if it doesn't? Wouldn't you just be planting the same stem over and over again, but just the top of it?
Depending on how much of it you have, you can replant the tips next to the rooted stumps then you can see how it propagates and if it doesn't happen you still have the nice topped portion remaining.
And yes it produces side shoots at the higher nodes towards the cut
