This is for when you have to ssh into some machine that's not yours, in order to do debugging or troubleshooting -- and you need your precious dotfiles while you're in there, but it would be not nice to scatter your config and leave it as a surprise for the next person.
This installs into temp dirs and cleans it all up when you disconnect.
Personally, my old-man solution to this problem is different: always roll with defaults even if you don't like them, and don't use aliases. Not for everyone, but I can ssh into any random box and not be flailing about.
Even with OP's neat solution, it's not really going to work when you have to go through a jump box, or have to connect with a serial connection or some enterprise audit loggable ssh wrapper, etc
