Well, sure. It specifies a consistent format, and the format reminds (or requires) the programmer to supply the necessary ingredients for maintainers who will come later. It seems to be missing a Description field, though. I have noticed that without a mandated format, coders will occasionally be lax in documenting functions. Possibly more important than which format is used, is to pick one and everyone follow it consistently. I don't know what your doubts are except, perhaps, that it is too elaborate. Personally, I like it, especially for a formal group project. An editor macro or template file will ease the pain, if you find it painful.
