Assuming this is Japan. Every train is that busy during rush hour. Waiting for the next one literally wouldn’t have helped. Also, Japanese train timetables are insane and missing one train can ruin your entire day, because you’ll miss all your connections, which could well include the Shinkansen because commuting between cities or even provinces on high speed rail is very common in East Asia.

Well, I don’t think this assumption adds up:

if your metro is so busy, i’m assuming you have trains running every 60-90 seconds

It could be running every 5-10 minutes and sometimes there’s just too many to fit into the current train, so they have to wait for the next train. And then if that particular man is in a rush, he won’t voluntarily get off nor do they want to forcefully pull him out.

At least that’s how it was pre-COVID in the nearest big city from where I live…

In a travelers.zip like this, I’m not sure how the one behind everyone is going to come out and has to go down several stations before. But this is a common scene in Japan, even though there are trains every few minutes. I think it could be alleviated during peak hours, by adding a few more wagons to the trains, this would be the most logical thing to do.
