They are, but if you look at Clubhouse's UI there are exact analogues to almost all of Pivotal's UI. Didn't Pivotal invent some of these terms, too? I could be wrong.
Here's a reference to most of the same concepts on the Jira site, for instance: https://www.atlassian.com/agile/delivery-vehicles/
(I've worked with Pivotal on projects in the past and I worked at Thoughtworks for a while, so we're definitely using language that should be familiar to users that are familiar with the flavor of "agile" promoted by those companies.)
