Care to elaborate?

There was this even in the Pentium Classic...

Yes, exactly so. Shorter pipelining makes for easier and shorter instruction dependencies... And so allowing overlapping instruction execution as has been done for a long time now.

The comment was more against the Intel Marketingspeak over-hyping the P4's hyperthreading. AMD's designs do the sensible things for keeping as much of the CPU as possible usefully busy. Intel's P4 hyperthreading is a complicated bolt-on extra to overcome problems introduced by Intel's marketing department's push for "bigger clock speed numbers must be better" (misleading) marketing push.
