Because people have been using a lot of emojis before LLMs in text already, and LLMs have been trained on those texts.
This whole "You have emojis in your text, it's LLM!"-trope got boring really fast. Amazing to see (and to think of the implications of) so many people apparently being in emoji-free social bubbles before this, though.

The channel has a few videos on it, not watched any other than this introductory one but some of the titles look interesting.
Also the introduction video above states an initial requirement of 'every PR must have a video' but it looks like that got dropped a while ago.
