Traditional Model activity, domestic, currency, economic

In Schweser, the two models show the analysis as:

Traditional Model:
Currency depreciation leads to long-term economic activity
Long-term economic activity leads to higher equity prices

Now in the diagram it shows the negative currency exposure arrow between 'higher equity prices' and 'currency depreciation'. Is the negative domestic currency exposure due to the higher and lower values in the diagram? Or is it related to the same domestic currency exposure?
