SEO hidden text and AJAX

Ok, I think this doesn't mean much and is a flawed experiment. The test url is: https://devx.lt/en/node/9 which contains ALL the content used in this experiment. All 9 tests are done on the same page, at once.

in the 4th experiment, he searches for "site:devx.lt GetJar is an independent mobile phone app store founded in Lithuania in..." and the result is returned WITHOUT any bold text. So this was a "most relevant" result, not a "found" case. Now the problem is, these paragraphs contain same words. Google returns "LinkedIn /ˌlɪŋkt.ˈɪn/ is a business-oriented social networking service. Founded in..." because, for one it at least contains "founded" part and further the paragraph I'm sure there is more. Since the results are limited to "site:divx.lt", and paragraphs contain same words, of course all 9 tests end with "found", as it is the only page close to being relevant.

I'd like to see the same test repeated, -NOT- all tests on the same page.

Some tests return bolded results, so I consider them to be true. I think 1-2-4-5 are false positives.
