Am I allowed to explain the source code publicly?

I am currently reading though the source code of Ue4 and I had the idea of doing an in-depth analysis of some parts of the source code. For example I would like to explain how the MovementComponent works in Ue4.

But in order to explain the logic behind some concepts I would need to be able to debug the source code line by line and I would probably exceed the limit of 30 lines.

Would this be legal?

As you’ve likely seen, the EULA permits public posting of UE4 source code for genuine discussion purposes in snippets of up to 30 lines in length. But one post could contain multiple snippets.

I forgot to add that I want to explain it in a video.

I think the same answer would apply to video
