Sounds like a good mix to me. I grow mine in mixes similiar to Paphs, except using peat instead of orchid compost as the water retainer.
I've seen similiar hybrids before, did he say whether its a highlander or lowlander? I think it would be fine in highland conditions as long as it doesn't get too chilly. highland temps range from about 25celsius during the day and down to about 12celsius at night. Which is the same for most of my orchids.
They grow in conditions very similiar to orchids, same humidity, like to be kept damp, and can be fertilised occasionally with balanced feeds. They like good light, but not direct.
I grow a few of these and they do make fine partner plants for orchids
