We use the Alpha component on the texture to increase the quality of the normal maps.

Worth mentioning that legacy compression was barely usable with normal maps, as it for most cases (not all though), leaked values between channels, leading to RGB to be not length of 1.0. Which lead to visible artefacts on normal maps.
