Does the dependent task/milestones across projects in a Master project get updated automatically?

Hi

We have a master project which has 5 sub projects in our PS 2013 environment. The milestones in the sub projects have dependency across projects with in the Master project.

Would like to know, if we update a milestone in one of the sub projects, would it automatically update the other milestone in another project (which has dependency)..?

Please suggest.
