What is my Ludisia Discolor doing?

[Blueszz]

I don't know if these growths will be taller. I own my Ludisia since January or something like that. I noticed it started new growths on both sides of the stem, but only one of them really grows.
I had new growths on stems that already were far over the rim of the pot. I was concerned about the weight the new growths would ad.
When the plants really needs to be watered, the stems are more flexible. You can bend it a bit upwards and give it support with a stalk.
