Afrika Korps Hills and C&CV2

[Blackcloud6]

I'm setting up Scenario 1 from C&CV2 which uses Afrika Korps map 1 and places hill counters to indicate hills.  The instructions are: "Place Hill markers in hexes 0515, 0701,
0901, 1602 and 1805."  I get what 0515, 0701, and 0901 are doing it creates a a 20 level hill for the dark brown bands of hexes and a 40 level hill for the Orange-Brown band of hexes.  But the 1602 and 1805 placement have me perplexed.  The dark brown band of hexes is one are as they connect at the tip of the depiction so why put two Hill counters in the same dark brown band? Or am I not getting it and because there are two hill counters it simply means this hill is also like the first, the dark brown is 20 meters and the orange-brown is 40 meters?

Thanks for your help.
