It could also be to let the applicant know what info on their site they may have missed.
I, for one, often find it difficult to know all that’s there and to not confuse what I read about School A with School B.
The fact that they are trying make it easy for ypu to fully explore their site doesn’t mean that they will consider that in an admission decision. What they may consider, though, is how well you articulate an understanding of the institution and your fit, so they may be providing the road map for getting the info you need to do that.
