More explanation needed about the step to remove the image

[irontribe]

File: engine/getstarted/step_six.md

Under "Step 2: Pull your new image", it says ",you need to remove the maryatdocker/docker-whale and docker-whale images from your local system."

It then goes on to use the command

$ docker rmi -f 7d9495d03763

I feel that 1) it's still not quite clear that this command only removes it from the local machine as opposed to the local machine and/or the repo. 2) From what I can tell, the -f flag is not explained. I did a $ docker rmi --help and found that -f forces removal. So I tried a plain $ docker rmi 7d9495d03763 assuming it would ask me if I really wanted to delete the image. Instead the image was deleted silently. So what purpose does the -f flag for rmi serve?
