Mysterious Japanese seating order

I feel sleepy on an ideal topic, so from now on, I will spell out specific topics and episodes related to them.
For reality, the company name and organization name are real names. I don't give out any personal name, most of it is beyond oblivion. .. ..

One of the meetings I will never forget is the meeting with Bank of Tokyo-Mitsubishi (at that time, now MUFG) at the head office.
I forgot the contents, but it was a very peaceful conversation. A memory that was called to collect information by a prospective customer who was not a customer when he was working at SAP.
This is 3 people. There are 5 people. However, at the beginning, there were only four people, and of the five seats, the second seat from the back was vacant.
Only one manager (likely older person) in the back seat was speaking, and one young man in the foreground was desperately taking notes. No one else said a word, including one who participated from the middle.
Why are 5 people coming out?
Why do you vacate your seat and take a seat?
Why don't you speak only to the elders?
When I started to worry about such things, I interpreted it as not being a business anyway, and it became ridiculous.
Sure enough, no business started after that, and it ended with "Thank you."
It's been over 20 years since then. Those who didn't say a word, I wonder what happened to them.
1. I became a superior who only spoke and did not let his subordinates speak.
2. I made my subordinates speak, write, and became an uncle and aunt who didn't work.
3. I quit the bank because I couldn't stand it or became ridiculous.
It's fun to have delusions, but it still feels strange.
Personally, I want it to be 3. If it is 2, it is historically valuable as the founding period of the uncle who does not work at this time (bubble joining group → proof of the uncle who does not work).
But I wonder if it is 1. Funeral style.
It was just after I returned from the United States, and I still remember it as an impressive event.
At the time of his arrival in the United States. "I didn't need attendees who didn't speak, wasted time, wasted coffee, and was ridiculed." The memory is still vivid.
