Question on using template: 'Workflows/MergeRequest-Pipelines.gitlab-ci.yml'

Just a question about how using the MergeRequestPipelines template works. Let’s say I use include: - template: 'Workflows/MergeRequest-Pipelines.gitlab-ci.yml' in b.gitlab-ci.yml and then I include b.gitlab-ci.yml into my main .gitlab-ci.yml. Does the workflow template apply to all jobs now?
