So he is absolutely correct, except that it absolutely does not matter in any meaningful way. No point in changing our practices as a result of this.

Standard deviations don't tell the whole story. You could have a situation where you don't see any triplets in charts but would see them in actual deep shadows in images, because spatially-correlated noise often has little impact on standard deviations.

There is no large-scale spatial correlation in the R5, though; its post-gain read noise is fairly random, with a fine horizontal banding noise, but it does not correlate vertically to create large bands.
