The bell-and-coat examples show two different timelines. Was putting on places Omar in the middle of the action when the bell rang; put on normally presents the action as the next event.
The idea
Use past continuous for an activity in progress at a past reference point. Use past simple to present an event as a whole or move a narrative forward. Two continuous clauses can show overlapping activities; the simple can describe a long completed event.
Examples
- I was carrying a tray when a glass fell.
- When I opened the curtains, rain was falling.
- When the bell rang, Omar was putting on his coat.
- When the bell rang, Omar put on his coat.
- We cycled for two hours and reached the lake.
- While I was sketching, my sister was taking photographs.

Watch out
Do not treat when and while as automatic tense switches. Meaning and viewpoint decide the tense. An event during an activity need not stop that activity, and a long action does not automatically require the continuous.
