Does Instagram apply any Bitrate restrictions on video upload ?

According to the documentation, creating video containers imposes some restrictions on the video's Bitrate which should not be more than 5Mbps. However, when trying some tests it seemed like we can upload videos of bitrates that exceed this value. Here is a link for the documentation: my question is: is this documentation outdated ? is it a bug that a video of any bitrate can be uploaded ?
