If you keep swiping left past the Manage | View | Clear menu, Clear expands to fill the width of the notification. If you release your finger then, it’ll trigger Clear. It’s pretty hard to do reliably, though.

There’s a similar behavior with the swipe gestures throughout iOS. In the Phone app, swipe left on a voicemail to show a Delete option. Keep swiping, and Delete fills the whole cell. Release when it’s expanded to trigger Delete without an extra tap.
