I think the OP might not be familiar with Ralfi's video style.
Ralfi films his stuff, but when posted, adds a verbal overview in the first ~30 seconds explaining the rest of the video. Said overview is recorded afterwards.
After the intro speech, he just shows the video + sound as it was recorded.
It's definitely not a review, and the prefix he adds clearly explains the issues are with him not knowing the module well aside from a view gripes like the RWR.
