Yes but you have to try all those things out so thats why that puzzle is trial and error. There really isn't any clue to decipher as to why some things work and some don't. There isn't a Evrika moment. Its just try random stuff until the button clicks. Quite literally.
it's not "random stuff"; there aren't many items in the area except for vases. you need only try to put the unique items onto correct pressure plates, which you can easily judge by their weights.
anyway, some RPGs have more and some have less puzzles and riddles depends upon the developers, Larian clearly is on the more side.
personally I dislike button hunts, but I like puzzle, riddle with clues.
