Is this Cypripedium exiting dormancy?

[CROrchid]

So, I've just received the Cypripedium formosanum rhizome with 2 "spikes". Considering it was traveling some 2 weeks by mail, I'm wondering if it's possible that it has exited dormancy (due being in warm conditions during the journey)? Photographs are in the attachment, notice that the top of the spike is greenish and the (onion-like) "envelope" seems to be pulled/broken.

I have put the plant in the fridge for the night. I can pot it but I'm not sure whether to do it tomorrow or wait a bit more (temperatures are already going over 5*C on some days here in Europe)? I guess if it indeed is exiting dormancy, then I have no choice but to pot it?

(P.S. This is my first Cypripedium plant, I'm growing Phals and Paphs mostly).
