If I understand you correctly, Safari does this on both iOS and macOS.
If you click a link that opens a new tab and swipe back from that new tab, Safari closes the new tab and shows you the previous tab.
I’m not exactly sure of the behavior when you open a new tab, then go to another tab, then back to the tab that was opened and then swipe back, though.
