I assume this is due to voltage spike from cranking which could damage the electical systems (although probably the donor car). I'm sure the cars can handle it but I would rather play it safe.

The idea is that when you connect the final wire, you will probably get a spark. The idea is that if you connect this to the battery, you *may* ignore the vapors, which could cause an explosion.
For this reason, you are meant to connect the last one up away from the battery, which you can do by connecting it to the body...
The voltage etc will be the same as your still connecting to the battery.
