They aren't going to bend neatly as a block if they are completely lithified. That they do bend together as a unit is evidence that they were all malleable, all of the same age, not millions of years apart.
Try putting an iron bar in a vise and squeezing it end-to-end. It will bend.
Then try the same experiment with pudding. Will it bend?
Then try it with a vise made of pudding.
