(The editing seems to suggest that In-ho was quick to enter from some shadowy corner after Gi-hun left.)

(And worth noting that in this combined sequence of past and present, BOTH Gi-hun and In-ho are questioning why Il-nam joined the games. Men with shared trauma who are really asking the man behind the trauma "why WOULD you willing suffer through this?")

Anyway, it's almost like it's foreshadowing a growing obsession with a certain man that will give In-ho his own reason to re-enter the games. I know a second season wasn't planned at this point, but it's neat how that just all falls together.

Especially because I got to wonder what's going through In-ho's head here as he's just staring out the window/at himself after closing Il-nam's eyes.

I think he's meant to be looking at the area where the unhoused man was, but the focus on In-ho's reflection also seems to suggest that he can't see beyond himself to the good in others.

Even standing in the same spot, he can't see in the world what Gi-hun did. And In-ho is quick to turn away from it.
