Server 2019 S2D Nested Resiliency - Storage Pool Quorum

$

On this page - https://docs.microsoft.com/en-us/windows-server/storage/storage-spaces/nested-resiliency - a scenario is detailed where a 2-node S2D cluster loses one entire node plus a disk on the second node. This results in 3 out of 8 of the clusters disks remaining online. The S2D quorum documentation - https://docs.microsoft.com/en-us/windows-server/storage/storage-spaces/understand-quorum - still indicates that to maintain storage pool quorum a cluster must have 50% + 1 disks available (with the pool resource owner counting as a disk vote). This is definitely the case in Server 2016... was this changed in Server 2019 and not documented? How does Storage Pool Quorum work in S2D on Server 2019 that it allows this nested resiliency failure scenario?

Thank you.
