Hi Vincent, if I remember correctly (which might not be the case), your expectation to see the unprovisioned device on both PIs is not correct. There can be only one "provisioner" on the mesh. By calling "create" on PI2 you are actually creating a new network.

I hope this helps.

Yes, provisioning is the action of joining a device to a network. The device can only be a member of one network at a time. Typically devices can only be discovered unprovisioned when they've been reset, like after rapidly turning a light bulb off and on some number of times. You certainly can use one device from two different computers, but both of those computers must be part of the same network. This can be accomplished by copying the relevant keys from one computer to the other. I did this to control a Sylvania light bulb that had been provisioned via Sylvania's app on my phone. After my computer became part of the same network, I was able to control the light bulb.
