Ignition only

I'm having trouble understanding the concept of firing the second plug
backwards.
After the spark jumps the gap on the first plug, isn't the "path of least
resistance"
going to be head-block-chassis instead of trying to jump the airgap of the
second
plug?? (compressed or otherwise). I'm probably missing something basic here.

TIA
Rod
944 turbo (+NOS and big Turbo)
only 7000 RPM so 1 coil 1msd. (sufficient??)
