I said "Of course, one should avoid that the same page is indexed with two different URLs.". I didn't say that these pages are always merged. However, in all cases I know (static pages, more than a dozen examples) these pages are merged. I don't know what the criteria to merge pages - at least it has nothing to do with luck. Perhaps the probability of merging pages is better for static than for dynamic pages. (Therefore, I said "espacially in the case descriped above", i.e. "/" and "index.html".)
