That's a very practical and straightforward way of addressing it, a really good idea.

In my case I very occasionally worry about having left the gas stove on in the kitchen after cooking, and what usually works, in a way similar to the pictures you take I guess, is re-tracing my actions just before and after switching the gas off. This way I can actually visualize how I turned off the gas just before draining the pasta in the sink or whatever.

This works if I remember something particular about that specific occasion tho, but it usually does the thing.
