Speed improvement with bitrise integration

Hi,
I am trying to use cocoapods-binary-cache with bitrise CI. I am using cache-pull and cache-push steps in bitrise workflow. cocoapods-binary-cache fetches the pods from the GitHub repo where binary version of pods are stored but it still compiles the pods. I cannot find any speed improvement by using cocoapods-binary-cache (as still the pods are compiled).
My understanding is that it should not compile the pods again. Am I missing something?
