Right, I forgot this. Sorry. So let's go back to your question:

The crucial point is `default-directory'. In my local environment, I
have for example
--8<---------------cut here---------------start------------->8---
(let ((default-directory "/tmp"))
(executable-find "emacs"))
"/usr/local/bin/emacs"
(let ((default-directory "/tmp"))
(executable-find "emacs" 'remote))
"/usr/local/bin/emacs"
(let ((default-directory "/ssh:ford:"))
(executable-find "emacs"))
"/usr/local/bin/emacs"
(let ((default-directory "/ssh:ford:"))
(executable-find "emacs" 'remote))
"/opt/bin/emacs"
--8<---------------cut here---------------end--------------->8---
You get the remote path only if `default-directory' is a remote file
name, and the REMOTE argument of `executable-find' is non-nil. And this
is understandable: if `default-directory' is not a remote file name,
`executable-find' does not know which remote host it shall use for search.
