Criteria google uses to show a double result from a site

[sstdesigns]

What criteria does google use when it shows two results from the same site one after the another.

Does any body has any ideas?

If there is more than one listing from the site that would rank for query in the set of results, they are groupped with the highest one.

Some pages of my site rank that way: one after the another. It happened when I have a group of pages (two or usually more) containing closely-related information AND they are heavily crosslinked.

More specifically, if two results are to appear in the same page of results: e.g. list of 10 results or list of 100 results etc, the second result is bumped up to an indented result behind the first listing.

So page A may be ranked #3 and page B that is initially ranked #10 will be bumped up to #4 as an indented result.

The criteria for getting a second listing are the same as getting a first listing... on page and off page factors.
