How can you undo the removal in Zsh?

Answer 1

You're misunderstanding. They're talking about undoing changes to the command-line, before you press enter, not undoing the results of a command.

Answer 2

The undo ability is a feature of the Z Line Editor, the editor that you use while typing at the command line. It lets you undo things you type on the command line, like any good text editor. But it won't let you undo commands that you execute.
