Shyvana dragon form and pink wards

Shyvana q acts as 2 separate hits correctly when hitting wards in human form. When shifted into dragon form I've noticed her ult q does not hit twice on pink wards. Ive not paid enough attention to regular wards to see if it happens here as well.

I'm curious if potentially her ult q is simply broken in general, and never behaves as 2 hits despite saying it should.
