MAB swiping vs doubling up on 3 string arpeggios sweeps

Playing Technique
#1

Here we can hear in slow motion at x25 speed how he plays the G string fifth fret twice, its sound like he is doubling up on that C note (I guess actually a B note because he is tuned a half step down?):

But now when he plays an inversion, the doubling up is gone, we can’t hear it at x25 speed. My guess is that he is swiping now muting the G string with the middle finger and maybe there’s right hand muting??? IDK

And on this tonic shape now the doubling up is more obvious again at x25 speed:

#2

Mike appears to systematically swipe when descending - arpeggios, scale patterns, everything. Even in the second inversion example, there’s this little lag between the last note of the triad and the first, where he picks through the muted G string with an upstroke, and then starts the pattern over with a downstroke and fretting the note.

He’s pretty accurate otherwise, and this does simplify things for the right hand…

EDIT: funny, though, having just watched the whole video: he straight up says he does not pick the first note twice. haha

#3

It’s also funny because when he demonstrates a sweeping arpeggio pattern starting on the 5th string with the pinky finger, on a previous section and video of the instructional, he actually does say he picks the bottom string twice in that scenario and actually even plays it slow, but then for the three string arpeggio he doesn’t acknowledge it.
