iTerm doesn't retain sessions at all. It just presents a facade resembling preserved sessions. Close iTerm2 while you have a tmux session open, or some SSH connections, or any long-running command. Those sessions and their processes die when you close iTerm.

Maybe iTerm can approximate some of those things if iTerm is actually running the whole show, i.e., iTerm mediates launching your tmux sessions and your SSH connections. But imo those features are underwhelming and oversold.
