Not to me

They are talking about dropping your elbow, something that relates to your stroke.
Dipping your cue, to me, represents dipping your tip at the end of the stroke. This can be an unconscious habit, or it could be the result of too long a bridge. The too long a bridge thing comes about from a player that unconsciously does not like to adjust his bridge hand for draw or low english shots, and so a long bridge where the cue dips naturally at the end of the stroke then becomes a habit. When I started playing 45 years ago, one of the 3 books I read about Pool said the normal bridge was from 6-8" from the tip, today, it states 7-9" is normal. Irregardless of what you think of 'standards', those standards are in place for good reasons, usually so you have the best chance to excel at the sport.
Another possible problem is that you are holding the cue too far forward with your grip hand, which produces a dipping effect when you grip hand can no longer to on a straight line and has to come up. Players that are not confident have a tendency to 'choke up' with their cue hand, thus giving them sum sort of false sense of security that their shot will be more accurate, and going towards trying to 'direct' or 'push' the cue ball into their shot instead of 'stroking' it.
I could tell your within 2 minutes if I could see you, and tell you how to correct it, but you would have to retrain yourself, and old habits are hard to break.
