Issues with protected branches: Github is confusing Pull Requests review and push protection

As a Github user, i want to request review for Pull Requests, but, i want to able push on branch.

Setup:
1) Create a branch
2) Protect it, asking review for Pull Requests
3) Do not protect push

Expected Behaviour:
1) Pull Requests require review
2) Push is open on following branch

Actual Scenario:
1) Pull Requests is requiring reviews
2) Got following error while pushing:

```
ramon@Ramons-Mac-mini:~/GIT/SAT-ROBOT (master)$ git push robot master
Counting objects: 2, done.
Delta compression using up to 4 threads.
Compressing objects: 100% (2/2), done.

Total 2 (delta 1), reused 0 (delta 0)
remote: Resolving deltas: 100% (1/1), completed with 1 local object.
remote: error: GH006: Protected branch update failed for refs/heads/master.
remote: error: At least one approved review is required by reviewers with write access.
To https://github.com/SymphonyOSF/SAT-Robot.git
! [remote rejected] master -> master (protected branch hook declined)
error: failed to push some refs to 'https://github.com/SymphonyOSF/SAT-Robot.git'
```

Start by reproducing the listed protected-branch setup and compare the expected behavior with the GH006 push rejection. The issue mentions no repository file, test, or entry point, so first determine whether the behavior belongs in this GitHub API wrapper or must be clarified as an external GitHub behavior. Done would require a confirmed scope and an actionable change or resolution.
