Benedict XVI is a complicated Pope, he does not fit very well into any sound bytes. He has made pushes towards some older ways, but he has also consulted with more modern-idea theologians early in his papacy. It remains to be seen if that meeting will lead to a shift somewhere in that direction in the future.
The RCC has usually moved in generations to centuries on some things anyways. I view him as a mixed bag for all sides of the RCC overall.
The article did give a good followup-reference in the “Instruction Concerning Certain Aspects of the ‘Theology of Liberation,’” mention. I found that on the Vatican’s website and it will take some time to go through all of it.
Only time will tell with what is coming next out of BXVI as he is a complicated person.
