I don't think that makes sense.
The wear occurs at startup because the engine isn't
lubricated. All the sitting has let the oil run off the
cylinder walls and out of the bearings.
If you are only stopped for a few minutes, the oil doesn't
run anywhere, and the starting is not particularily harmful.
I'd be willing to bet that the thousands of extra revs would
do a lot more wear from all that needless idling.
