Git = a tree. Most (all?) labels refer (directly or indirectly) to a node in the tree. A node is identified uniquely by an SHA1 hash, which is generated from both the file system contents and the meta data. A node can have both N parents (google octopus merge) and/or N children, though the norm is 1 or 2 parents and N children, with N usually = 1. The files you see are just the physical representation of the node. You can move around in the tree by referring to labels or hashes directly. You can manipulate which node a particular label refers to by various commands such as commit, merge, rebase and reset. Labels exist as, at least, local branches, remote branches, tags. There is no magic. You’re probably over complicating it in your mind.

I just moved all of my godaddy domains, which I’ve always resented having, to namecheap due to their promotions and support of organisations against SOPA. SOPA will cripple the internet if it goes ahead. Of course, godaddy’s corner of the internet is so slow and unintuitive that it’s already crippled. Poor service, poor site, poor ethical values, poor pricing, just generally shit, or as they say here, mierda! Adios you worthless bastards.
