That's an old one but I wonder where it comes from.
I suspect it comes from a knowledge that in a crisis people tend to revert to a single known pattern of operation, and teaching PPLs one thing to do in the event of an engine failure "trim for best glide" increases the likelihood of them trimming for best glide instantly, rather than thinking about all the permutations of best glide -v- slowest sink rate and crashing.
