Yes, you can see in the detailed Boeing charts (page 5 of the chart supplement) that at 1-dot high GS, the PAPI was on path (two whites, two reds).

As the plane reached 2-dot high GS, the PAPI became slightly high (three whites, one red). At this point the PAPI deviation was only 0.16 degrees. This is consistent with that the co-pilot reported.

The co-pilot was slow to correct and allowed the PAPI to reach four-whites, some 400 ft after that point. I believe the GS was at full-deflection as this point (there's some discrepancy in the Boeing data).
