No Phase-coherent multitrack audio warp quantise

Hi Folks,
So happy to see phase coherent group editing free warp option. However in the manual it say that multitrack audio warp quantize does NOT maintain phase coherence… i dont understand why ? Is it because each track has its own warp marker and phase coherence warp work only with warp point that indeed is common to all the track in the folder being group edited ?

Thank you
