Why did Boeing opt for that particular one? It's a style and operation akin to those on the DC-10/L1011 but quite unique for them. The rest of the 7X7 series use the type that rotate/slide when opened to rest outside the frame.
Were they copying the other manufacturers? Or were they trying a concept in anticipation of future aircraft; but subsequent dissatisfaction caused a rethink for the 777 and 787?
Thanks!

I don't get it. Would you please explain it?

In case of a heavy impact resulting major deformation around the door, the door may jam around the guide rail..
The chances of this kind of situation happening do seem very remote though..
