High on the firewall is better for a catch can than at battery level IMHO. The AOS doesn't care since the oil dumps back into the sump, but in theory you want as much oil that collects in the hose to drain back where it came, not into the can.
The single line (vertically) on the AOS returns to the intake.
If you think about it, there should be no pressure differential anywhere inside between the block or heads since they are all connected by huge oil galleys that flow way more than any hose could. My belief is that the majority of the people with catch cans that filled up where not due to the alleged pressure issues, but bad downhill hose routing to low mounted cans.
