Yes, but it's not what you think - when you did this, what actually
happened was that the client on the machine you started from did:
ssh my.office.machine "scp file.pdf my.home.machine:"
That is to say, you really just copied the file from office to home
without it ever touching the machine in the middle. So if the two end
machines can't see each other, this won't work. And if you can't arrange
to get the password/key/passphrase for the home machine from the middle
machine to the office machine, this won't work.
