How interesting. I didn’t think differential clocks where a thing back then.
Or maybe they’re not differential and they’re just routed together because it’s convenient. Since they store with coupled inverters I can see why having both phases could be useful in some flip flop implementations.

The two clock phases don't overlap, and act to "pump" the signals through the circuits on each half-cycle. Circuits from that era effectively use both edges of the clock, and the use of simple pass transistors instead of full flip-flops simplifies the implementation.
