Please help me. What does the Prof. Walter Lewin mean by this "that is that rho of s"?

If I take this wire and I make a cross-section of that wire-- this is wire 1 and this is wire 2-- then at any moment in time, as the voltage wave passes by, this may be positive, that is that rho of s, and this will be negative, that's that rho of s .
