The minimizing single thread losses is in reference to a module design.When 2 threads run on the module there is a 10% penalty when compared a single thread running on a module(this implies actually that single thread performance will be better by those 10%).It has nothing to to with minimizing single thread losses compared to present design(aka 10h).They are simply stating that the integer core grouping in Bulldozer does not hinder much the "strength" of the single threads running in parallel on a module(10% is the penalty).
