Oh yes, this is how it is supposed to work.

the `command` syntax evaluates "command" on the spot. It is analogous to the
eval command (which performs a complete globbing). So `cat foo` will read
foo, and then evaluate the wild cards which were in it. Thus the * gets
evaluated right away. On the other hand, setting the var to 'this is *'
prevents the * from being evaluated right away, because it is protected by the
single quotes. It is evaluated only when you do the echo, because by then it is
unprotected by the quotes.
