Phalaenopsis Keiki doublet

[pbphut]

One of my Phalaenopsis plants has decided to reproduce, but I have a dilemma. One of the flower stalk branches developed a Keiki on either side of the branch and each one threw a root, but now it looks like a third root is growing between the two plantlets. My question is whether it's better to split the Keikis into individual plants or is it alright to attempt to grow both plants as one. I realize that most monopoidal orchids are grown as singles, but do doubles do as well? Any potential problems as the plants mature?
