I find some explanation around this:
Tip #1: Order matters for caching

However, the order of the build steps (Dockerfile instructions) matters, because when a step’s cache is invalidated by changing files or modifying lines in the Dockerfile, subsequent steps of their cache will break. Order your steps from least to most frequently changing steps to optimize caching.

One thing more, could you please give more data on how these changes are useful for the cache deps?
