I know what you are talking about Traci!!!
I noticed if the roots in good condition in moss and you transfer it in bark they will do fine, might set back a little but in general do fine, but if its not in great shape than its more challenged... and its up to the plant to decide which way to go. Also they say its better transplant when new roots emerge.
I tried to add some moss, not even 50:50, maybe 90:10. did not work for me. the area close to moss stayed too wet too long and if roots were there they got rotten.
I bought few plants and they are in moss but people said do not repot until new growth starts to grow so I mange to water it safely and they are doing ok for few weeks now of course with orchids few weeks its not long but I keep my fingers crossed they will be ok .
