OTEL logback appender ignores additivity?

[den850x]

My logback.xml defines a custom logger that has additivity="false", and the OtelAppender is configured for the root only.
But the messages logged to MyPrivateLogger are still getting picked up by OtelAppender.
Is this expected?

 <logger name="MyPrivateLogger" additivity="false" level="INFO">
        <appender-ref ref="Console"/>
 </logger>

  <root level="INFO">
    <appender-ref ref="OtelAppender"/>
  </root>
