The alternator has diodes in it (electrical check valves) which allow the current to flow out of the alternator when it is charging. Unfortunately, they also allow current to flow through the alternator when the battery is connected backwards.
I can draw you a schematic, but I think that any further attempts on my part to explain will result in confusion (mostly on my part.)

you can tell me anything out want about electricity, but the alternator still only charges the battery and keeps the car running, the battery starts the car though
without the battery the starter cant crank the engine, so if the altenator went the car should, at least for a while, crank until the battery dies

Simple, This is why the main fuse or alternator fuse would blow if the battery were to be connected backwards (basically a dead short in the alternator.) Fortunately for him, the main fuse blew, protecting the rest of the electronics.
As to the leak 'moving inside' I would attribute this to the heater core (which was probably damaged by the excessive effort that was required to remove the hose.)
