These videos were likely recorded at the bare minimum two days to over a week ago. Sources are saying he stayed at this hotel for a week, whereas he's clearly staying in some sort of house in those videos since it has a giant backyard. Plus, the picture of him and his girlfriend we know is from July 2023 and has been posted by him prior to today.
You can post any pictures or videos to your snapchat story at any time no matter when it was recorded or taken. His team likely has this scheduled or put it up just to have something on it. Considering his girlfriend left Argentina two days ago, it's clear these have been delayed considering she is in the videos and she's not in the country.
