You are correct. You will still require to take part in the ICAO English Assessment regardless of your English background. Not only do you have to possess a proficient level of English, but you will also need to be able to comprehend English with a slight accent (which you will encounter when flying international). Don't worry, I thought I did mediocre (eventhough I'm a native English speaker) but I passed the assessment anyways.
From my understanding, here is how the new Stages are set (for HKG, not sure about internationals):
Stage 1
- JKI Test
- Reasoning Test
- Personality Test
- HR General Interview (No Tech)
Stage 1.5
- ICAO English Assessment
Stage 2
- General & Technical Interview
- Mental Math Test
- Flight Planning
- Group Exercise
Stage 2+
- Medical Exam
- Flight Grading
