Think about mauls and you'll figure it out yourself 

[Byrdi]

Also overhead attacks are slower than any of the other attack directions.

[Turboflex]

1v1 an overhead best used in turning situation so it is harder to track and a bit of a surprise to opponent.

Really, I think it's just because you can't turn into it, which would technically make it slower.

[Nordwolf]

Basically you can't hiltslash with overhead and that may look slower sometimes.

[WITCHCRAFT]

The animation is slower than other swings, and you can't turn your character to one side and make the hit connect faster. Weapon speed and WPF will increase the swing.
