CVS question (HEAD and dev)

I guess this is a beginner question :-)

I created a project and committed some files and even tagged few official releases.
Lately I committed new code and expected to get a nightly snapshot dev release of the module
But I see that the dev version contains the initial version and not the latest code I commited

using

Retrieve the initial version of my code instead the latest changes

In drupal's book I found this

Creating a development snapshot release of your module
... This will create a "dev" snapshot which will always point to the newest version of the module in a particular branch.
To do so, make sure that the module is branched for the appropriate Drupal core version, and then create a release node pointing to that branch, rather than a specific release tag.

Is it possible that my dev release is not pointing the DRUPAL-6--1 branch?
In the release page it looks like it does..
Please see hide_submit 6.x-1.x-dev

What am I doing wrong?
