MacSeth, MC also denied a lot of things before and they proved to be true, including the update for the algo in relation to caffeine.
The proof is in in the logs, searches and SERPs. When you watch G*'s movement for years, you learn from a lot of mistakes, but you also become familiar with at least a generalized pattern regardless of the times updates take place. Updates may differ, but there was and still is a similar pattern, the only difference this time, the new infrastructure which is the largest so far they have acquired. what I meant by re-index is going round spidering all links, adding to them as they go while most of the stale links in the index are stripped from their filter and trustrank until they re-appear in the new index (caffeine). Once they appear again, they'll have their new calculated rank and backlink profile (this is also diffrent from all previous updates). What MC means (not read anywwhere his denial by the way) is we don't have any data that has been lost resulting in re-indexing the whole thing again.
Yes, there was a shift in the site: and inurl: command numbers today on G*.com. The was also a shift up and down of the link: command (backlinks).
So things are still changing, increasing and decreasing and with all that a ranking process according to new algo rules!
