She is exactly right, that method worked for me. I would just add to choose a parking lot with a slight slope, so you can get the clipping in part down first without having to pedal.

I know lots of people swear by always using the same foot. I force myself to practice using either or both feet. Saved me from a nasty fall once.

I dread the day I have to give up my clipless, I have a mobility problem with one ankle and sometimes can barely turn my foot. Then I will be one of those people who advocate for clipless but ride with platform pedals.
