This problem is a direct application to Bertrand’s Ballot Theorem here. Read the proof by reflection method for understanding.

Yes, the approach is based upon André’s reflection method.
I think almost everything is covered in this editorial - so you can safely skip reading it from there.

Is there a mistake in this equation in the explanation?

Ways=(x1+x2+y1+y2)C(x1+x2)−(x1+x2+y1+y2)C(x1+x2+(c−1)).

For me it should have been:

Ways=(x2-x1+y2-y1)C(x2-x1)−(x2-x1+y2-y1)C(y2-x1+(c−1)).

Maybe, I misunderstood the first part of the explanation…
