How do Documents Center and Records Center alleviate list view threshold?

It is found that Documents Center/Records Center templates being listed as one of several methods to circumvent the list view threshold restriction in SharePoint(SQL truly).

I also understand now that if a single list vie is used in Documents Center/Records Center, the threshold (5000 by default) still applies.

Question - How do Document/Records center solve the issue then if the restriction still there? Is it because these template offer a "searching/querying" interface vs. "browsing/traversing" interface? If that is the case, in essence, if a regular document library is used, as long as it is not showing the list view but have user search for it, would it achieve the same result then?

I was under the impression that doc/rec center stores more documents than normal documents? If so, is that the only true advantage using doc/rec center vs. regular doc lib as far as solving the threshold issue goes?
