in2it54 please look at www.oneworld.com/ffp/lounge-access. This defines access for short haul/long haul and Long haul/short haul flights. It is clear that it is the class of the long haul flight that determines lounge access. The OW rules do not cover long haul/long haul and Short haul/short haul. QR grants access to lounges according to ticketed class, effectively the class stated on your boarding pass. However as stated it is thought that QR will grant access to Al Safwa for arrivals in First where there is a business class onward flight.

With regard to the old Premium Terminal I was told that passengers arriving on regional F could have access to the First lounge if they were traveling business class on Very long haul. Others have stated that access was also granted for all onward long haul business when arriving in regional F.

OT: One curious thing is that QR define long haul as 6+ hours whilst OW define it as 5+ hours. This has cost at least one member of this forum access to Al Mourjan.
