Modifiers affect the preceding character or grouping so in the first example the modifier is attached to the character '8' and in the second example the modifier is attached to the parentheses which will affect the entire contents of the enclosing parentheses. Also note that \d is a subset of \w so anything that matches \w will also match \d.
