That doesn't rotate the lot - it just rotates a house (or multiple houses by SHIFT-clicking).
Terrain paints, floor tiles and other objects outside the building(s) are not rotated.
In my case (probably the same as the opening poster), the lot is facing the wrong way: When I bulldoze it, the mailbox is at the opposite end to the road and faces away from it. (Then when I place any lot on it, the imported lot facing the wrong way).
Will there be an update with the ability to rotate a lot when placing it, like in Sims 3?
