Blending differently masked layers

In this exercise, we are going to take that more aggressive mask that we created…in the previous exercise, and we will use it to introduce another copy of the…model into the landscape background, and then we will refine the mask, so she…looks very nearly at home.…And I'm going to click on RGB here at the top of the Channels panel to revisit…the color composite image. And then I will scroll down the list, and Control+click,…or Command+click, on the thumbnail for that final overlay painting channel.…And notice that there are two channels with the same name,…so make sure you select the one at the absolute end of the list.…

Then switch back to layers channel. You should see a lone base layer with no…layer mask. Drop down to the Add Layer Mask icon, and go ahead and click on it to…add a layer mask to that layer.…Now right-click inside the Image window, and choose Duplicate Layer, and change…the Document name to Multiplied model, which is that background image.…And then I am going to name this new layer M2, for model 2, and click OK.…
