Dear Sonja,
I see and yes, you are right, there is a mistake in indices.
The correct sentence is "... where w_1 = v_1, w_t = v_2, and w_p, ..., w_q are the neighbors of v_k in G_{k-1}." It means that w_p, ..., w_q are the vertices of G_{k-1} and are the neighbors of v_k.
Thanks for pointing it! I have already uploaded the updated version without the mistake.
Best wishes,
Oksana
