What on earth are you talking about? They do entirely different things! MLS is an E2EE protocol, whereas Matrix is effectively a conversation-syncing protocol which supports multiple E2EE mechanisms, including MLS.

Source: Guy who started Matrix, was in the room at IETF 101 when MLS was proposed and ratified it for Matrix, and has been working away on the various approaches to use MLS on Matrix.

If Matrix now supports MLS, you should ask the site owner to update this: https://arewemlsyet.com/

Based on my inspection of the Rust crate [0] as of today, it does not. YMMV.

Separately, as you well know, Matrix has its own encryption (Olm, Megolm) that competes with MLS for group chat use-cases. Why you are acting like it doesn't is beyond me.
