Difference between Tasks.ReadWrite and Tasks.ReadWrite.Shared in Graph API (planner)

Question

What is the difference between "Tasks.ReadWrite" and "Tasks.ReadWrite.Shared" permissions in graph API?

From the documentation:

Tasks.ReadWrite:

Allows the app to create, read, update, and delete the signed-in user's tasks and task lists, including any shared with the user.

Tasks.ReadWrite.Shared:

Allows the app to create, read, update, and delete tasks a user has permissions to, including their own and shared tasks.

To me, they sounds almost identical.

On a related matter, can a planner task really be "shared"?
I have not found a way to share a task without sharing the plan. And if you share a plan, all users in the team get access to all tasks in it.

TL;DR Use Tasks.ReadWrite, Tasks.ReadWrite.Shared can be skipped for Planner.
