Naming is the hardest part :) It's a snapshot in the same sense as the ZFS file system, or a Network Appliance file server. What's hard here is this deletion policy can be used for things other than hot backups, eg protecting commit poings so you don't hit Stale NFS File Handle when searching over NFS, keeping a point-in-time searchable commit point alive with your index at different stages, etc. http://blog.mikemccandless.com/2012/03/transactional-lucene.html goes into more detail.
