Problem with the Y Method

[Raven72]

I was working through the beginners methods in the wiki and am struggling to grasp/understand steps 4 and 5 of the Y Method which states:-



Step 4: Adjust Swap Count of Remaining 5 Edges

• We would like to solve the remaining edges with Y-moves in a standard prepare, Y, restore conjugate. Such moves do an even number of edge swaps. Therefore, first count the number of edge swaps that we need to perform.
• If even, proceed to Step 5.
• If odd, perform a quarter U-turn, then proceed to Step 5.
• If confusing, count again after the single U-move. Or solve one or two of the edgies, and then count. Correct with single U as needed.
• This works because a single U amounts to an odd number of swaps.

Step 5: Solve Remaining 5 Edges

• Use Y-moves and symmetric conjugates like U Y U' to move and flip edge cubies in the top layer and the workspace edge in the middle.
• Make sure to only do an even number of U quarter-turns to preserve the even swap count created in Step 4.
• Straightforward because we can focus on a single edge cubie and how to move and flip it with Y.
• There are minor restrictions on the order in which we solve the edge cubies. Start with solving two adjacent edgies in the top layer, say the two in the back away from the workspace. Adjacent and not opposite to each other because Y works on adjacent cubies. In the top layer because we need the workspace edgie until the end.
• Straightforward also because after solving 3 edges the remaining 2 fall into place automatically. We cannot get stuck with a single swap missing because in Step 4 we made sure that there is only an even number of swaps. If there is a mistake, simply redo Step 4.
• With 3 of the 5 edges solved and the last 2 edges in their correct position, either we are done or we need to flip those 2 edges in place. This is a standard application of two Y-moves.

I was wondering if there is a video anywhere to show what is going on with the even/odd swaps to place the final layer edges and last E layer edge??
