In Eshell, ${cmd} expands to nil.
e.g.
$ echo ${/bin/echo -e "foo\nbar"}
$ 
Note the absence of any output from `echo'.

$ echo ${/bin/echo -e "foo\nbar"}-foo
nil-foo
n$ 

`*echo' prints expected output, but only for the first case.
$ echo ${/bin/echo -e "foo\nbar"}
foo
bar
$ 

$ echo ${/bin/echo -e "foo\nbar"}-foo
("foo" "bar")-foo
$
