The point wasn't quite the same (didn't involve "source"-ing .zshenv). 
$0 doesn't work if used inside startup files (.zshenv/.zshrc/.zprofile). 
When you source it manually, it's not treated specially.

Just wanted to note that the '%x' that I pointed out does work, though:

## as the first line of .zshenv (so, will be run when starting zsh)
$ sed 1q ~/.zshenv
echo in .zshenv 0=$0 %x=${(%):-%x}

## results in:
$ zsh
in .zshenv 0=zsh %x=/home/bhaskell/.zshenv
