Show git commit logs only for a specific remote?

Question

I'm using git 2.3.0. and trying to find 3 latest commits on a remote repository myremote.

$: git remote
origin
myremote

I would expect that the command

git log -3 --decorate --remotes=myremote

would achieve what i want. However, I can see the logs that are not strictly from myremote.

Example.
$: git remote
commit 63d8a59f6 (myremote/branch1)
...
commit 63d8a59f6 (myremote/branch2)
...
commit 63d8a59f6 (origin/branch3)
...

In the above example, I would expect not to see the anything from origin.

This is a subtlety of the functionality for --remotes:

   --remotes[=<pattern>]
       Pretend as if all the refs in refs/remotes are listed on the command line as
       <commit>.

Git is looking at the commit hashes for branches from myremote. But since your origin/branch3 also is pointing to a hash from a myremote branch, it shows up in the log output.

Functionally

   git log --remotes=myremote

is the same as

   git log <hash1> <hash2> <hash3> ... <hashN>

where each hash is taken from the contents of the files in .git/refs/remotes/myremote/
