Maybe English is not your first language. Read your sentence again:
If you don't think that's clearly condescending to the OP, then we'll agree to disagree. And then you're flatly wrong. Go to 3:33 on the OP's video and watch him fan the clutch for 3 gears downshifting into Les Combes at the end of the front straight after Eau Rouge, perfectly matching revs. That's not the only place he does it. So he uses different techniques where he sees fit. Pretty advanced riding.
Regarding the EBC, its main function is to limit engine back torque when on trailing throttle, adjusting the rate at which the rear wheel slows in comparison to the front wheel - which causes the rear to slide - and can be used to adjust attitude of the bike entering a corner if the rider has the requisite skill. The slipper clutch present in all 1199s is the primary method to reduce the differential between engine speed and gearbox speed when down-shifting, again reducing the abruptness of the rear wheel slowing down more than the front, causing a slide. Lastly, have you lurked enough to know the OP and his modifications to his bike? They are
extensive. He's running a different engine management system and perhaps even an adjustable clutch. Again, I saw it working fine for him and his pace.
No one asked you to criticize, so if you're going to, at least be specific and try to be at least correct. E.g. this gem from your rebuttal:
You think the ECU is a magical "black box" that will automatically match your revs to the next lower gear when you downshift like a Ferrari 458 Italia? It is the choreography of feet and hands working the clutch, throttle and gear shift after sufficient practice that produces a matched-rev downshift. The ECU is simply providing air/fuel mixture based on environmental conditions and sensors in the bike when you twist the throttle, nothing more. Even EBC uses algorithms of throttle openings executed on trailing throttle to modify the characteristic of engine braking.
A separate system with dedicated ECU is capable of auto-throttle blipping to specifically rev-match, but does not come on any OEM bike:

See above. You have repeatedly proved yourself a riding technique troll. I'll let you in on something. The
truly fast guys don't critique unless they're
asked. I've read your riding critiques on other threads here and frankly you don't come off as someone that actually has the experience of what you attempt to malign others for not doing. You probably have attended a few schools, made some huge strides in your personal ability, maybe even been bumped up to the next group at your track days recently. Your arrogance betrays your neophytism as does your erroneous discourse on the topic. So I'm adding you to my ignore list.
