Reasoning for the custom post status of ‘private_post’ rather than using ‘private’

Hi,

Is there a reason that the post status ‘private_post’ is used instead of the default WordPress status of ‘private’?

A client of ours has been setting the questions as private from the back end post edit page, and wondering why they are not appearing on the anspress dashboard where the label shows ‘private’. I have realised this is because the posts status needs to be ‘private_post’ to show here.

Is there a better way to set questions as private in the backend, or does it have to be done from the front end for the questions to be set with the ‘private_post’ status?

Thanks for your help!

Matt
