Yeah, similar. There's one guy I ride with who always has his entire torso a bit twisted to the left when he rides. Even though this is only evident on the bike (he walks straight), I hesitate to bring it up b/c maybe he has some injury or deformity and it's not just a question of poor posture. But those aside, I'm sure his power values are highly asymmetric.
Your ankle guy might also have an underlying health reason.
