Dota 2 – Cancelled Clarity Potion After Nyx Spiked Carapace

dota-2

As the title suggest, I'm wondering how the mechanics of Nyx's ability Spike Carapace work with regards to damage block.

I saw a video recently where the Nyx had an active clarity on himself, was then auto attacked by the enemy but used Spike Carapace to block the damage from the attack. This still cancelled the clarity.

Is that by design? Is that a bug? Or do I just not have the right understanding of what is blocked or how the attack is blocked with Spiked Carapace?

The incident in question happens at 4:47, and the streamer asks the question too.

Attacks that deal no damage will still interrupt the effect of Clarities, Salves, the healing from Urn of Shadows, and anything else that is cancelled by being attacked by a player. Other examples are an Urn of Shadow charge being dispelled while the hero is under the effect of False Promise, Oracle's ult, which delays all damage until the end of its duration, or being attacked while under the effect of Guardian Angel, which negates all physical damage.
