Sated Mordekaiser Q Bug

So, I know that sated Morde sounds really stupid and bad but before you judge me just hear me out. This is morde's Q desription.

Mordekaiser's next three basic attacks deal bonus magic damage, with each subsequent attack dealing a multiple of the previous attack's bonus damage.

So shouldn't that make it so that when he is sated his q will apply 2 stacks of on one hit when he is sated. It should work because it says the next basic attacks, but it doesn't. This is really annoying because if it did work it would make morde broken as heck in the jungle. You could get 3 stacks with only 2 hits. I would love a red response on this to tell me if this was a mistake or if it was put in intentionally. Even tho it says that it is his next 3 basic attacks I don't think it is coded that way when it should be because it doesn't apply sated stacks.

How to replicate:

1. Pick morde and smite
2. Build devourer
3. Get sated
4. Press Q and start attacking something
