Confusing or not, the reliance on multiple signatures as offering greater security than single relies on the independence of multiple secrets. If the secrets cannot be shown to retain independence in the envisioned threat scenario (e.g. a user's compromised operating system) then the benefit reduces to making the exploit more difficult to write, which, once written, reduces to no benefit. Yet the user still suffers the reduced utility arising from greater complexity, while being led to believe in a false promise.
