The author is very smart. He hasn't addressed PAF directly, in fact this article more or less advocates to Eurofighter's WVR capabilities (which are no-doubt world class) against the F-16. Now in the light of facts here are some answers to this article.
1. PAF never participated in AE2011. However PAF did participated in ATLC later in same year (but NATO didn't participated in this ATLC held at UAE)
Following link on AE2011 says:

2. NATO has documented its participation in multinational exercises
here. There is no record of AE-2008-4 but two other exercises AE-2009-2 and AE-2009-4 are listed. PAF participated in them too.
3. During
Exercise Spring Flag 2008, Turkey participated with Italian (NATO) Eurofighters. Following is a kill mark photo on Italian Eurofighter.
The dogfight of Italian Eurofighters and PAF F-16s was just one small example that got limelight. There have been lots of more similar encounters in ATLC, AE and FalconTalon Exercises. I wish Alan Warnes or any other writer shed some light on them too. World should see the true potential of our pilots
