My statement was ambiguous. Your clarification and example is much clearer, as 
the following reveals:
$ IFS=: wrapper "hello world" hello world
<snip>
"$*"
    hello world:hello:world
<snip>
"$@"
    hello world
    hello
    world

For programs which use : as word separator, "$*" will pass all its arguments 
as a *single argument* separated by colon so that the program itself can split 
them into separate arguments. For programs like squeakvm that don't have 
argument parsers "$@" will pass them as space-separated *arguments*. In both 
cases, spaces within arguments enclosed by quotes will be preserved.
