In the more advanced method of solving edges on large cubes, the rows that make up the centers are not aligned in between each edge pairing. This is faster, but means that care should be given to not moving anything that would affect the orientation of a not-aligned side. This especially comes into play when you're building an edge (on middle layers) and a piece you need is found on the top or bottom layer. This video addresses how to move that edge piece away from the top layer without mis-aligning the left side of the cube. It specifically deals with an edge piece that has a different color on top as the edge you're building has facing you. (See this video: [ Ссылка ] for what to do when the colors are the same.) Although this is shown with a 4x4x4, the same principle holds for larger cubes as well.
These videos were done for my own benefit mostly, but if they help others as well, great.
