Top of new Dendrobium shoot changed the way it was growing

[mark467]

I have a dendrobium that I have had 2 years now. Growing in the same place with same water and fertilizer routine. I have had 3 new stalks grow and bloom. After a bloom from a stalk the don't bloom again (yet). This summer a new stalk started to grow and then the leaves stopped it grew the stalk more and now a small cluster of leaves (not just one like I am used to) is growing in a different direction. Is this normal? I will try and attach pictures.
