Cattleya schilleriana adjusting

I got Cattleya schilleriana at the end of September potted into plastic pot with sphagnum, so I really needed to repot it. But since they are known to be quite sensitive to repotting during the wrong time of the year (fall is wrong, spring is right) - I was somewhat worried about its adjustment.
Apparently worried for nothing. Newest pseudobulb started to grow several roots at once.



Another observation - the newest leaves are getting more reddish purple in color then when it just arrived. I am not sure if it is supposed to be or plant gets too much sun and I should move it to a shadier spot.



Plant descriptions on the web mention that leaves undersides are purple, but in my case it is the surface too. I don't know...
