Hopefully 650ib will chime in, but I'll try to address these questions in the meantime based on some of his statements in the comments section.
Regarding the tuning of each bike, it appears the HP4 in this video has a PC5 and is using a custom tune for the Brock's exhaust he is running. The Panigale is running the Racing Evo map that is provided with the Termi's.
The other dyno pull you are referring to is in his original comparison video. It took place at a different time, day, location, and dyno. It was not compared back to back with the Panigale in the video, but he does mention that both bikes feel equally fast, which this latest back to back dyno comparison corroborates. Here is what he stated specifically:
"The dyno that produced 197HP uses STD smoothing, has massive fans in the room which produces more of a ram air effect and the tuner is really good. Both dyno's are great and all I was looking for was a comparison between both bikes. I'm pleased to see that my precious Panigale R has almost the same HP and 10lb ft more torque than the HP4."
