I've also seen snow tires perform worse than all-season tires, e.g: https://www.tyrereviews.com/Tyre/Michelin/CrossClimate-2.htm vs https://www.tyrereviews.com/Tyre/Barum/Polaris-5.htm

If tires complying with the standards overlap, then the standards are meaningless. When there's requirements for snow tires, but not for X brand or model of snow tire, than it's not doing any good. That's why it's important to have a snow rating that can apply to tires of any type, and if it meets that rating, regardless of the rating for dry warm weather, than it should be good to go, otherwise not.

That's a pointless comparison.

1) The Michelin is 120 euro tire, vs the 60 euro Barum

2) The test page says nothing about the test conditions in which the tires were tested.

3) The Michelin tire test explicitly states:

     The testers explicitly recommended against standardizing cars with all-season tyres in Sweden, suggesting that drivers would be better served by dedicated summer tyres paired with proper winter tyres when the season changes, rather than this compromise solution that fell well short of true summer tyre performance.
