Without looking at a wiring diagram, you're probably correct that the horn wiring should match between the two horns, and likely the black should be connected to ground for both horns. Keep in mind though also that often the horn fuse is the same as the accessory outlets (aka "cigarette lighter"  so a fuse that's blowing could also be due to something plugged in to those.
The horns have a voicecoil, similar to a speaker, and therefore you will have a low resistance reading through a working horn. It will be low resistance, but not a dead short. That is likely why you are questioning if all terminals are effectively shorted to ground. If you set your meter to measure resistance instead of continuity you will likely see a few ohms of resistance through the horns.

Also, any idea why it took so long for the fuse to start blowing? We estimate that had been miswired for a couple months before it started blowing fuses. The horn fuse was blowing immediately as soon as power was applied (ignition turned on), until miswire was corrected.
