I tend to agree. Problems can arise if there's too much of a delay. Orchids have the wonderful advantage of being forgiving in the sense that they don't always noticeably react negatively right away to incorrect stimuli or environmental factors.
Act now and you can catch certain problems in time. Wait too long and bigger problems may come to pass.
I always feels it's a great precautionary measure to see what's going on with your plant anyways.
However, I'll add that in my experience, Phals just don't do very well potted in full on moss. Moss creates problems with retaining too much moisture for much too long, and drying out unevenly, as well as compacting. This is a serious problem that leads to the suffocation of the roots and ultimately root damage or root loss.
My recommendation if you want to go the potted route, is to use a clear plastic pot with lots of drainage holes and use large grade bark as a potting medium.
Of course there's always the mounted route.
Just as an additional bonus, I'll throw in the info that Phals don't naturally grow upwards like how they're presented to be in stores. They grow horizontally, thus if you see your Phal drooping over the edge of the pot, it's normal. It just wants to grow the way they grew in the great big wild.
