It's a bit confusing because this isn't really the Return of 1.0 Talents, but Talents 4.0.
So the "hybridization" comes from the left tree, which apparently is also your mechanic for learning all your abilities. So you can choose to invest points into making a "hybrid" by taking tanking skills like Avenger's Shield and dps skills like Crusader Strike. Or healing spells and DPS spells.
But yeah you will still spec into one specific thing and that's where you get the "utility" tree which is the spec one.
