It would make sense... however it will be 2... The reason is the snapshot that gets created off the base vm, that will then allow for fast provision, does not get deleted - this saves time one the next create from this item.
In ascii art -
To start:
BASE (1:chain)
With One Link From: (both are chain 2)
BASE + SNAPSHOT (this is what happend to the first vm so the "snapshot" can be copied)
BASE + COPY_SNAPSHOT (this is the new vm)
Delete the "new vm":
BASE + SNAPSHOT (this is left)
