to hear what other experienced yogis think of this 3rd event in his practice history. (...But the 3rd is...?)
Have you met this person in person? Regarding that "3rd event" there's nothing in-person pointing to something noteworthy there. It is noteworthy to them---the practitioner in your video link---and that person's point is clearly just that their own meditation has changed their life. Why should there be more than that for any viewer of that account?
To make use of the ox-herding parable: a suffusive, thorough practice by oneself en
courages the practitioner to take up exactly the unknownness and the wholesome creativity of their own vast, brief life and releasing the easy gratification of moving in the trench of another ox, so to speak.
YouTube, for example, abounds in evidence of people living lives extraordinarily (which can be very simple), contributing to the wonder of their own lives and sometimes in the view of others. What does it take to live one's own life? Repeated close observation in one's own life/mind/views and some regular freedom from one's own blinders/ patterns. There's a lot of simplicity in that.
And that takes time. It's is not easy. Comparably, to watch another's practice, their structure, their apparent life and to want to mimic it---to climb a known ladder, that's a natural move towards something easier and gratifying (relates to craving and clinging in a dharma model). If one can render that "teacher"'s life special, that can make a person feel better about their own move towards mimicry-gratification.
One outcome of suffusive, sincere meditation practice is to en-courage one to be alive without a goal of parroting and with a deep interest in life itself as one experiences it themselves. What teacher needs that in their followers? Meditation is like a four-year degree*** after which one takes it and applies it to own-life under lab conditions of care and close observation. And, yes, those first decade(s) of work are sometimes parroting...
Maybe that is not happening here, but that's my thought when I see people perseverate on what xyz-person has done.
--------
***to take the analogy further, perhaps the 4-yr degree is just the arena in which to get some basic meditative proficiency and that first release (technically, I think Gotama says it can take seven days to seven years), and then after stream-entry starts the personal thesis of to what activities should I specifically apply this knowledge (comparable to the massive effort of getting lost and found in a PhD). Many people may be stickily inclined to apply themselves to the dharma circuit, whereas I'd say join the dharma teaching circuit in retirement, be made a teacher only if there are students who will it, after a life of another application, or become monastic. Otherwise, one gives their dharma practice and steadying efforts to some activity(ies) worthwhile and suited to one's being.
