No, mgh is not the same in the two cases. In trial B you slid the entire weight m off a shelf that is at the starting height of the piston. (Say it's 50 cm above the bottom of the cylinder.) In trial A, you move small weights off a succession of shelves of *gradually decreasing heights* so that each weight is slid off onto the piston at the instant that they are at the same height as each other. Ergo, less work was done in trial B.
