If you look at it as a minor scale (like C↔Am), 3 becomes dominant, and if you set it to 3~, the semitone raised becomes the leading tone to the root note of 6, and if you set it to 3~7, it becomes tritone (triad), so it progresses to 6 more and more. It seems to be easier to progress to 6. I have no idea, so I watched the video and tinkered with InstaChord a bit and figured it out./villagepump/nishio.icon
First of all, with InstaChord, it's usually displayed as C/Am.
Since 1 is C, this is a major scale
At this time, 3 is Em and 6 is Am.
In the minor scale, Em is dominant and Am is tonic
In other words, going from 3 to 6 in a major scale is the equivalent of going from dominant to tonic in a minor scale.

Compared to the major scale, the minor scale has a weaker dominant to tonic connection.
Because it's not moving in semitones relative to the base note of the tonic.
3~ing in the C/Am state is to E the Em.
Em becomes E, which means So becomes sharp.
3~→6 would be a semitone shift from So# to La
Also, in the Seventh Chord, the Re is sounding, so the So# and Re make a tritone.
