all the ice had been removed.
However, all bets are off if an insufficient amount was applied.
Anti ice fluids prevent ice and snow from forming on the wings, not act as a slippery substance that make the snow slide off the wing. In your case the HOT had expired.
I have flown for hours after deicing and i still had fluid dripping from the wings after landing.
