In both sheets Create a drop-down list (microsoft.com) is used to fill data, perhaps How to make Excel Data Validation Dependent Lists (contextures.com) is used to link them. It's very poor quality of the video and not a lot of details what is in background.
If the question is what exactly is on video that's better to ping an author in comments. If you have similar task it's better to illustrate it with sample file indicating desired results.

@LeLoT3 , you are welcome.
google "excel dependent drop-down list", you'll find a lot of samples, perhaps more close to your concrete case. I gave the link on first what appeared.
