There's a lag of one CTB line for SAO behind deblocking filter, except for last line. However, once SAO has been completed on a line, all its pixels, i.e. up to y+ctb_size are filtered and ready to be used as reference. Without SAO, when deblocking filter finishes a CTB line, only the bottom bottom 4 pixels may be filtered when next CTB is process by the deblocing. The await_progess for hevc then checks whether the bottom pixels of a PU requires access beyond that point, so the reporting should effectively report up to the the above limits.
