OpenZFS caches disk blocks in-memory in the adaptive replacement cache (ARC). Originally when the same disk block was accessed from different clones it was cached multiple times (one for each clone accessing the block) in case a clone planned to modify the block. With these changes OpenZFS caches at most one copy of every block unless a clone is actually modifying the block.
