Strange way of how bbox is split

[jose1711]

I don't really understand what's going on here. This is my original bounding box:

22:01:28 Splitting bbox [48.7024040222168, 17.77560806274414, 48.733848571777344, 17.802509307861328] at lats 48.72439193725586..48.727508544921875; area decrease 20%

Then after processing this results in some completely unrelated areas:

22:01:28 Splitting bbox [48.727508544921875, 17.77560806274414, 48.733848571777344, 17.796794891357422] at longs 17.776657104492188..17.79244613647461; area decrease 12%

The idea is, when you split an area in two vertically, some bounding points are left in one of these parts.

What concerns me is result of the overpass query (from a really tiny bounding box):

Or is this a problem of overpass-turbo instance itself?
