In brief: Stress
Sometimes when diabetic patients undergo stress (prolonged exercise for example) stress hormones (cortisol and adrenalin) can increase glucose.
However it is still important for him to follow up with his doctor because it does not appear that the exercise he did was particularly stressful. In general patients with type 2 diabetes experience hypoglycemia (low sugar) in response to exercise.

In brief: Complicated disease
Diabetes is a complicated disease and often doesn't work the way we expect.
You'd think that after exercise, the blood sugar would be good - but he could run a marathon and still have an elevated blood sugar after. It's a combo of how much Insulin he's producing and his muscles' sensitivity to insulin. Over weeks to months of exercise, he will see a change in his fasting sugars, so keep it up!
