Yes, the local part should let you type any command name that would work 
if you were in the home directory[1] for that connection. I'll also add 
a note about that to the manual (and a regression test).

Oops! Somehow, I got it into my head that we had an 'eshell/ssh' 
builtin, but that's not the case. I'll just remove this paragraph.

[1] Well, whatever the default directory is if you ran "cd 
/method:user <at> host:", anyway. Personally, I'd avoid trying to use 
relative paths though; I think that's a bit confusing.
