This is a good question, and I hope someone on here has the knowlege to point us in the right direction! I'd like to know as well!

If I were to guess (and that's all it is), there'd be a second copy of each texture when the map is exported. This copy is scaled down, so it can be loaded quite quickly. The down-scaled textures are drawn until the larger ones are asynchrounously loaded.
