git scm poll doesn't ignore changes with pipeline

We are using the job as attached with the groovy test.groovy file. We poll the SCM for changes but want to ignore any change that is in our jenkins-jobs git repo. This is because in a full setup we poll more repositories which do change. In the jenkins pipeline we use .* as exclude region. This does work unless we clone the same repository in our test.groovy. There we say poll=false, but the repository is polled and at the moment we make a commit to jenkins-jobs.git the job is run. With these configuration we would expect this job to never run, even when we schedule it frequrently
