ICE is known for being fuzzy with its holds. They issue them over sketchy name collisions and inaccurate or outdated charges in their databases. It's one of the factors in why a bunch of cities don't cooperate with ICE -- they hate getting sued over it when it happens.

E.g. https://www.latimes.com/local/california/la-me-ln-ice-detain... from back in 2017.

That is to say, this is mostly a story about ICE doing what ICE has always done, getting attention because of other prominent cases. Deservedly! Because ICE is a pretty awful institution in practice.
