methinks it is because you can put an compound statement there,
and stringliterals or numberlitterals can easily be inserted?

setInterval('alert(1);alert(2);', 300);

but:

setInterval('doIt();', 300);

can more nicely be written as:

setInterval(doIt, 300);

as only the pointer value is stored then.
