A question about a recipe: Baked Ricotta and Goat Cheese with Candied Tomatoes

I have a question about step 6 on the recipe "Baked Ricotta and Goat Cheese with Candied Tomatoes" from TheRunawaySpoon. It says:

"For the tomatoes:

While the cheese is baking, heat the olive oil in a large skillet over medium heat, then drop in the tomatoes. Cook, stirring frequently, until the skins on the tomatoes start to split. Pull the pan off the flame, add the vermouth and return to the heat. Add the brown sugar and herbs and stir until the sugar is melted. Add a generous pinch of salt. Lower the heat and cook gently until the liquid is reduced to a syrupy coating for the tomatoes. The tomatoes will collapse and some may disintegrate. That’s fine.
