I haven't used ClearCase, but from the description, I don't think it's much like a view. It's closer to IntelliJ's changelists, but without many of the limitations.
It's effectively a way to take changes you're making and pretend like you did them in worktrees without having to switch back and forth.
Or maybe, to work on several branches, achieve the merged state you want, then split the work up into reviewable branches that can be merged in any order to achieve that final state.
