E-TTL should compensate for wherever the light is pointed, provided the flash is powerful enough.
ETTL means the flash sends out a pre-flash microseconds before the main flash during which the camera/flashgun measure the light and make an adjustment for the main flash before it then fires, so in theory it doesn't matter where the flash is pointed.
