They both look great, nice healthy looking roots. Now keep in mind that moss and I are not friends. I only have one plant that's in moss and that will be eliminated as soon as it's done blooming. First thing I would do is ditch the moss and repot in bark or coco husk. I prefer coco. It works better for me than most other mediums in my conditions. If you decide to leave it in the moss for now water
SPARINGLY. Check the roots every time you water and make sure you don't see any that start looking black. That's a sure sign of root rot. If you start seeing that don't wait. Repot immediately.
I have to disagree with Tsuchibuta about fertilizer. Lack of adequate, regular nutrition is one of the main reasons orchids don't rebloom for most people. Lack of adequate light is the other reason. I know first hand. I have 3 large phals that I've had for a couple of years and I could never get them to rebloom for me. I started the 125ppm N about 6 months ago and feed at every watering. They are all in spike now and one is even double spiking. JMO
