Two Phalaenopsis planted in one pot

[cra323]

Hi all! The newbie needs more advice

My husband brought me home a phal. the other day that he bought from Lowes. It is a beautiful plant, but it needs some help. Upon closer inspection, it looks as if two phals. were planted in one pot, and the moss was packed really tightly. Most of the roots (that I can see) look decent, but there are several that have dried up and have hollow tips. The flowers are in the process of dropping off, so I'd like to repot this if possible.

My main question is: should I separate these phals in separate pots, or repot them together? And what about roots that look firm and healthy, then are dried up for a couple inches, and then look firm and healthy again towards the tips (hoping that makes sense)?

P.S.- told the hubs that from now on he's only allowed to buy me orchids when I'm around )
