Thats because you are reusing the cell that is created using dequeueResuableCell.

Compare reload 1 with reload 2 for other cells too ...You can observe that 

postercell-0 in reload1  = postercell1 in reload2
PosterCell-1 in reload1 = PosterCell-2 in reload2
PosterCell-2 in reload1 = PosterCell-0 in reload2.

The cells are just being reused!
