The incorrect/confusing text was fixed, so this has been marked status-completed.
In terms of the conversation in the comments around allowing suspended users to follow or unfollow posts, that would indeed be a separate feature request because it's not a bug and is operating as intended.
The Community Team reviewed the comments around that, and determined that reviewing what actions suspended users can/can't take is a bigger issue. In order to properly dig into that, we would need to review all actions that suspended users currently can/can't take and see if there is a good rationale for making any changes there. This is something we've put on our backburner, but isn't an initiative that we are planning on focusing on in the near future.
