Like shining you watch in somones eye vs trying to shine you arm in someones eye, the watch will be brighter because of the reflection, whereas the arm is more diffuse.

To contradict you, the ISS can flair, I have observed on a number of times
I may not be as dramatic as an iridium flair but flair it can
