Sure, but if I search for one of those people, and I am confronted by a bunch of unrecognised sites, plus those four, I have two choices.
1) Go for the site I know has sufficient info for a quick summary
2) Click a site hoping it will have better than 'sufficient' information on it.
You might do the second, but the vast majority of users will do the first. So, if you are Google, do you make those users happy, or do you insist that there is some higher purpose than satisfying them.
Conversely, if you did not want a brief summary, and wanted in depth information, you are highly likely to click through several entries anyway- possibly (shock!) onto the second page.
