I think that this statement may not be correct. Max glide range occurs at L/D max for both jets and props (I know that max range is not L/D max for a jet, but we are talking about glide performance here). When considering jet performance, this means that max glide range occurs at minimum drag, which is the bottom of the thrust curve (i.e. Vmd).

From the book "Flight Theory for Pilots," :

For jet aircraft, the following performance items occur at L/D Max:
- Minimum drag.
- Max engine-out glide range.
- Max climb angle.
- Maximum endurance.
