Junior was never known to be the deeper searcher. It was always known that depth in Junior has a different meaning. depth in shredder8 also has different meaning relative to depth in shredder7.04 because (otherwise Shredder8 could be at least 100 elo stronger than Shredder7.04 based on the difference on their search depth).
