It's perfectly reasonable to have multiple exported/destroyed pools with the same name. Pool names are unique only when active on the system. This is why 'zpool import' also prints out the pool GUID and allows import by ID, instead of just names. In your output below, you'd see that each pool has a differnt ID, and you could chooose your pool based on this information, and optionally rename it to a non-conflicting name when you actually do the import.
