We're not disagreeing with the presentation, you're misunderstanding it.

No matter which protocol you use the packet only has one destination, the destination IP, so it does not go through the slow path on any hop on the way just because its ICMP. When a packet hits the TTL limit on a hop it will go through the slow path as the CPU will generate the response ICMP. The protocol used for traceroute makes no difference here.
