Sharpen Blade/Bladestorm

Question. Can anyone confirm that if you have sharpen blade up and are running the legendary unhinged, that the two mortal strikes thrown in that bladestorm will be hit with the sharpen debuff without consuming the cooldown? Someone was also saying storm of destruction also applies the sharpen debuff to all hit?

The first ms from bladestorm with the lego should consume the sharpen and OP buff, the 2nd ms would be unbuff, but the ms will be affected by sweeping strike if you have it up to hit 2 people. Storm of destruction aint affected by sharpen, just the normal healing reduction that ms apply.
