Do you think he wants to provide values that correctly describe the report patches as shown on a computer display?
My reading of it was that D50 is being used because that's standard for ICC profiles. But you should pose your questions directly to Florian on his DCG forum here.

Initially, I wanted to know how the 493 sample patches were chosen.
The verification patches consist of the typical neutral and color axis luminance ramps plus a number of randomly distributed patches [not aligned with the profiling patches] to test the robustness of the calibration. The number of random patches you use is somewhat arbitrary but users have found that several hundred up to 1000 have been sufficient to get repeatable assessments across a variety of displays.
