Repetition in puzzles

I've noticed a lot of repetition in the puzzles, even as I progress in rating points. Is this intentional? For example, I see at least two dozen back rank check mate puzzles per day, same moves in the same sequence. Unless this is intended to build some sort of muscle memory/pattern recognition, I don't really understand the point of solving the same puzzle over and over..thoughts?
