Look into two separate architectures for the same image at the same time? #1612

I was going through the docs and I found this(https://crazymax.dev/diun/providers/file/) :

I was wonder if I can look into more than one architecture of the same image for updates.
I ran a container using this :

# Static list of images for Diun file provider
# https://crazymax.dev/diun/providers/file/

- name: node:20-slim
  platform:
    os: linux
    arch: arm64
- name: node:20-slim
  platform:
    os: linux
    arch: amd64

It did not give any errors in the console. I just wanted to ask it is correct.
Thank you for your help
