No, the 970 is long and fat, combining the strengths of both approaches.
It has multiple pipelines along with many stages for each. The many stages of the P4 turned out to be a blessing in one way, allowing the P4 to get extremely high speeds. The fat pipes of PPC and Athlon allow them to compete with the P4 (PPC not as successfully however due to other issues). Now, what happens when the fat pipes get grown tall?
That is what the 970 has done.
