git.reactos.org doesn't see newest change in PRs

As seen here :

https://git.reactos.org/?p=reactos.git;a=shortlog;h=refs/pull/1034/head

opposed to that :

https://github.com/reactos/reactos/pull/1034/commits

Or am  just too impatient ?

Because of this, I am unable to force a build on buildbot with the latest commit.
