The term "hai" from Olog-hai and Uruk-hai may mean that those Uruk-hai and Olog-hai contain more" human" perks such as the  intelligence aspect  in comparision to the standard orc or troll.

The Uruk-h ai for once are mentioned to be as strong, or slightly stronger than one of the Edain kindred; the Olog-hai yet are stronger to all their cousins.

Both Olog-hai and Uruk-hai far obviously (well . . not really) are much smarter than orcs who are just on a battlefield to swarm it, despise all savageness and there is still a not fully atrophied mind.

Both are resistant to sun,the  Trolls do not turn into stone and the Uruk-hai are not weakened, although every Uruk (Black Uruks for example) react the same way against it, but they are a case apart.

So that was what led me to such beliefs..
