When using /setblock to place a dispenser with a rotation datavalue, if the front of the block is against a wall the dispenser will point the opposite direction when placed.
To Replicate: Place a block. Attempt to spawn a dispenser one block north of it, with a rotation data value of 3 (Telling the dispenser to "look" south). The block will instead face north. Same happens for east/west.
