Why is it a compliment to Matt when Attean does not lead him back to the cabin after his visit to Attean's village?

In chapter 19, Matt is invited to Attean’s village by Attean’s grandmother. She was impressed that Matt, a white boy, would save a Native American’s dog. On this trip to the village, as before, Attean shows Matt the way to the village. During the visit, it is clear that Attean and his tribe accept Matt. He feels as if he has gained their respect.

In the past, after visiting the village, Attean walked Matt all the way back to his cabin, showing him the way. However, Attean has been teaching Matt how to track his way through the woods as the boys went hunting, fishing or to visit the village. This time, when leaving the village, Attean only travels with Matt long enough to take him across the water in his canoe. Once there, even though it is dark, Attean lets Matt out but does not follow him as before to walk him back to the cabin. Matt realizes that Attean believes in his skill and abilities to make it through the woods alone. This respect from Attean is a compliment to Matt.
