I still think that you're a little confused. The reflog is a "history of where this branch has pointed since the repository was created/cloned." If I clone a repository with a history of 100 commits on the 'master' branch, the reflog for the 'master' branch will only have one entry. You can completely delete the `.git/logs` and still run `git log` successfully.

Here's an example:

  $ git clone blah
  
  DAG:
  
    A - B - C - D - E
        \
         Z - X - Y
  
  
  Branches:
  
   master => E
   topic/new-feature => Y
  
  
  reflog:
  
    master
      E - clone from blah
  
    topic/new-feature
      Y - clone from blah

Notice how cloning a repository with an existing DAG doesn't populate the reflog. It just give it a single entry saying that the branch was updated from 'nothing' to whatever commit it was pointing to remotely.

Now let's change where 'master' is pointing:

  $ git reset master C
  
  
  DAG:
  
    A - B - C - D - E
        \
         Z - X - Y
  
  
  Branches:
  
   master => C
   topic/new-feature => Y
  
  
  reflog:
  
    master
      E - clone from blah
      C - reset to C
  
    topic/new-feature
      Y - clone from blah

Notice how the reflog is a history of the values that the branch was referencing, but is not the history as what you get when you run 'git log'. After the reset, 'git log master' would show you commits A, B and C, but A and B are nowhere in the reflog.
