Leave it as it is now! I had the same dilemma with Dendrobium phalaenopsis (i know, different plant, just telling what might happen). The plant flowered continuously four spikes, approx. 2 years. I thought, that wasn't healthy, better stop it. So i cut the 5th spike as it appeared. I did much wrong, as all of the leaves fell off and growth was inhibited for a year. Nothing happened, naked canes just stood there sulking. It is all right now, it grew new cane (and is flowering again, crazy plant
I'm quite sure that all this happened because I roughly stopped it. So, just relax and enjoy your orchid
