The edit protection has been disabled therefore "Is edit protected" cannot be used to protect entity pages from unauthorized editing.
"Is edit protected" is a predefined property provided by Semantic MediaWiki to indicate whether editing is protected or not. While any user is qualified to add this property to a subject, only a user with a dedicated permission can edit or revoke the protection to an entity after it has been added. This property is pre-deployed (also known as special property) and comes with additional administrative privileges but can be used just like any other user-defined property.
