Wow, that is indeed quite strange - that’s a very high speed for having scraped along a 9000 foot runway.

They either landed extremely long or it rhymes a bit with the Pakistani Airlines accident of an attempted gear-up landing go around a couple of years back, both not implausible in the context of already dealing with a bird strike. There are also edge cases where the plane won’t yell Landing Gear at you, and it‘s really really hard to get a 737 to a point where you can’t lower the gear anymore (multiple hydraulic systems failing, gravity pins and pulleys as well, Stig Aviation did a great video on that.)

Pretty sure there was no EMAS, as the plane dips down into the dirt at the end of the runway right away, ie not that much lift, and EMAS would do orders of magnitude more arresting.
