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.

Under display settings, both monitors are set to display a launcher bar. Auto reveal works fine with the mouse on the primary (left) monitor. The sticky edge works fine with the secondary (right) monitor, but no auto reveal for the launcher bar. I can bring up the secondary (right) monitor launcher bar with the super key and alt+f1. So far I've reverted to Nvidia 3.04 drivers from 3.19 by purging from terminal and re-installing to no avail, and now back to 3.19 and it's still not working. Ubuntu 12.04.4 LTS 32-bit AMD Athlon 64x2 Dual Core Processor 6000+ Nvidia GT630 PCIe 2GB RAM Any outputs you'd like from me, please let me know.
