He just want to keep you busy for the next year.
I have an exhaust brake and when on CC and it reaches about 7 mph over what it is set for the exhaust brake comes on. Works great. Otherwise as stated, downshifting works well also. Just apply the brake to get down to a reasonable speed for the transmission to kick in when you downshift.
Typical rule of thumb is to go down a grade in the same gear, or lower, than you went up. Sometimes though there isn't an "up," just a down or vice versa.
