Will the flower spike(s) of a keiki survive after transplanting?

[Berrybee]

A friend has a phal orchid and a keiki growing out from an old live flower spike. Yesterday she cut the whole spike and gave it to me, so that I can have a new plant, and she's hoping after cutting the old spike, a new spike will grow out. But when I looked at the cutting, I noticed a spike just started to grow out on the keiki, still a very tiny tip. And it looks like another spike going out from the other side.
In this case, will the flower spikes survive? What should I do to increase the chance of surviving? Can I remove the keiki and pot it? Or should I leave it on the spike cutting? There are 2 knots below the keiki. Right now I put the spike in a container with some water.

Suggestions are greatly appreciated!!
