无法查看远程git repo上的最新提交

Question

I have a local repo with branch X, which is associated with a private GitHub repo branch X. There are two "remotes" added, origin and backup, both pointing to the same GitHub repo (using https).

If I do a git log origin/X I see the most recent commit is 826d562 from May 2nd. If I do the same with backup/X , I see dc32de2, d78498c, f3ed5a8, 16f7c17, and then 826d562, with the others from 5/15 to 5/6.

IOW, it shows more recent commits that I and others have pushed to the remote repo.

I created a VM on another machine, setup the same remote repo, did a fetch and checked out branch X and it too, shows 826d562 as the HEAD. A coworker on his machine, sees the dc32de2 version and all the others.

If I go to GitHub and look at this branch on the repo, it shows the latest as 826d562 and not dc32de2!

Why do I see (or not see) these newer commits on the remote between the various machines?

Why do two "remotes" pointing to the same repo, from the same machine, show different things?

I'm totally baffled!

Along the lines of authentication expiring, I did some Googling and came across this command:

git credential-cache exit

I did that, and then did a fetch, and got an update. I did "git status" and it says my branch is behind, so I rebased and now when I do "git log" I see all the recent commits.

I'm using https to access the Github repo, using Ubuntu 12.04 as my OS in all cases. If anyone has thoughts on the reasoning behind what is going on, I'd love to hear it, but it does work now on the other system.
