I think the parent meant that you need to check if these commands are executed properly, otherwise you get into trouble later. For example, if the toilet paper isn't added to the shopping list, and you go shopping with this list the next day trusting it contains everything you need, you're not buying the toilet paper. Similarly, if the timer is accidentally set to 100, you only notice it after, say, 20 minutes when there's black smoke coming out of the oven.

I know, that's why I said you get a quick confirmation - "Ok, setting a timer for 10 minutes." is spoken back to you via the speaker.
