I can confirm the same behaviour. The "super" key method works fine. My launcher is set to reveal when the mouse goes to the top left corner but it does not behave that way on the external monitor configured to the right of the laptop monitor.
The behaviour appears to be top left of the entire display area rather than "per monitor": switching the external monitor to be left of the laptop monitor allows the launcher to reveal as expected on the external monitor but not on the laptop monitor. WM_CLASS for the launcher is "not found" as shown by "xprop WM_CLASS" and clicking on the launcher bar; presuming "unity" package.
