Sure, but in both examples all images are left floated but they behave differently.

The top edge of a floated box can never be higher than the top edge of another floated box that precedes it in document order (ie. appears first in wikitext). That's true of both pages. Typically you have this problem when a big infobox pushes down a right-floated image (because they are both right-floated) and that image pushes down a left-floated image (because of the top edge rule).

In other words what happens is that when a float gets pushed down, all following floats get pushed down as well - the first float stays on top of them. The infobox pushes File:Sturnus cineraceus - feeding - Japan- 2014.ogv down (it's actually defined at the very beginning of the article) and the left-hand images are pushed down to stay below it.

When all floats are all on the same side, this kind of chained pushing effect is exactly how you would expect the to behave; but for those which are on the other side, and look unrelated, it's very unintuitive.

There are workarounds for this at varying levels of crappiness; you can wrap the infobox and the video in a single floated div, you can reposition the video, I think there is even a script around that does that dynamically, but none of those are great, and dumping huge blocks of non-text into an article without any kind of organization is just not a very good way of creating a readable document.
