Are Task Implementor buttons making the wrong thing the easy thing?

[jdhines]

The docs clearly say it's important to use /clear between tasks, but then the UI provides easy one-click buttons to go to the next task:

When using these buttons the chat is not cleared, so my question is: should they even be there if do what the docs specifically say not to do? Or do the buttons actually clear the context (but just keep the previous discussion above)?
