In your command above, the current shell is interpolating $PATH and
sending the remote shell the literal current path and not the literal
string '$PATH'. This is because the single quotes enclosing $PATH are
themselves doubly quoted by the current shell, and thus, are not
metacharacters to the current shell.
ssh -t some.random.host "echo '$PATH'"
ssh -t some.random.host "echo \$PATH "
The first line of output will be the path of the current shell, and
will begin with 'FOO:BAR:BAT:'. The second line of output will be the
path of the remote shell.
(Or did you want the remote shell to get the value of the current shell?)
