These are valid blocks under the old consensus rule. AFAIK, there is no mining of fully invalid blocks going on here.

That's probably because no-one's produced a fully invalid block with sufficient proof of work, but supposedly the pools involved would quite happily have built on top of one because they're skipping block validation almost entirely.

BIP 66 changed the definition of validity. These blocks are fully invalid.
