Your comment had me intrigued so I had to test this.
I use Logic mostly under DAE but today I used it with CoreAudio/MOTU 828 MkII.
I copied an identical drumbeat on two different tracks and then I ran one of them through I/O into a bypassed Portico compressor.
Now the results: Without PDC, there was an audible delay, with PDC engaged - there was comb filtering.
Even with PDC engaged I still had to nudge the 'Portico track' by 122 samples to get acceptable result.
However, I still didn't get 100% phase cancellation when flipping phase on one of the tracks. It was pretty close but I could still hear some very high freq content. I assume it has something to do with MOTU analog circuits.
