Jacoco report in JUnit report output directory

I have a simple Maven project configured to generate a JUnit report with the Surefire plugin, and a coverage report with Jacoco.

After running mvn test, I expect to find:

1. jacoco report files in reports/jacoco
2. surefire-report.html in reports/junit

However for some reason the Jacoco report files appear in both the reports/jacoco AND reports/junit folder:

Please help me to understand and correct.
