The value of a fixed time constant seen in all simple RC circuits also extends to circuits with multiple resistors (and one capacitor). That time constant is fixed. Once you introduce another capacitor (as per your schematic), the "fixed" time constant mentality we have when there is only one capacitor, becomes flawed and inapplicable.
