Valentine Scalpel beaten by air grab

[Yummy Bubbles]

I'm not sure if this is an issue or if I'm just confused about what happened. I was playing against a lovely miss sally kit ballard, and while we were hopping around me as cerebella, her as valentine, I jumped and tried to air grab, before it landed she used Scalpel, as soon as val released the scalpels, the air grab hit and cerebella was invincible through the super, BB who I'd called as an assist was still hit by the scalpels so I know that they came out. So I'm trying to figure out exactly what happened. I found the replay in beta and it still doesn't make a lot of sense. Any Ideas?

Grabs make you invincible. Everything about this is normal. You just got lucky.

Most supers are invincible on the same frame the first active frame comes out to prevent this sort of thing.
Air scalpels are not though.

So if a grab connects on the frame the scalpels come out, I think priority goes Throw > Scalpels Hit but you're already invincible so whatever.

This isn't the case with ground scapels however.
