"last_files_match_only=true" only adds one alias as a reviewer, regardless of number of edited files

[jamoor-moj]

Problem

Currently, I have a repository with the action setup to have last_files_match_only=true. When I open a PR with multiple files edited inside the PR that each have their own alias associated with them, I would expect that a single alias for each file edited would be added to the PR.

codereviewers.yml

files:
  'include/client.h':
    - jamoor-john-doe
  'src/**':
    - jamoor
  'src/client.cpp':
    - jamoor-test
options:
  ignore_draft: true
  last_files_match_only: true

Actual Behavior

Context

Based on the PR that added the last_files_match_only=true functionality (#80), it looks like the intention was to have the files section of codereviewers.yml to match the behavior of github's codeowners file.

I've setup a test repo (https://github.com/jamoor-moj/codereview_demo) that I can compare the behavior of codeowners and codereviewers (which is where I got the screenshots of the behavior above)

Codeowners: jamoor-moj/codereview_demo#4

  include/client.h @jamoor-john-doe
  src/ @jamoor
  src/client.cpp @jamoor-test

Codereviewers: jamoor-moj/codereview_demo#5

files:
  'include/client.h':
    - jamoor-john-doe
  'src/**':
    - jamoor
  'src/client.cpp':
    - jamoor-test
options:
  ignore_draft: true
  last_files_match_only: true

Is my understanding correct that this was the intention and therefore this is a bug? Or was that not the intention and this is an enhancement?
