I don't have much to say that you don't know after 49 years in the saddle.
I would like to help you understand the Physics behind what you have explained.

Normally, three things are perfectly aligned: front contact patch, center of mass (bike plus you) and rear patch.

Whenever we are decelerating, regardless the brake or engine-braking effect that is applied, the center of mass is trying to move ahead of the front contact patch.
The friction of the rear patch is preventing that from happening.
Any minimum steering input from you will make the C of M to swing one way or the other, as the friction of the rear contact patch becomes marginal.

Regarding leaning and breaking while going downhill:
The front contact patch is being overloaded and is close to the limit of total traction (longitudinal and transversal).
Loosing the front is easier than in horizontal curve and moderate acceleration conditions.
