A user on Morpho borrowed 46k USDC with a 500% borrow rate

Hello everyone,
Being quite involved in DeFi, I wanted to understand Morpho and their vaults, and how they work.

Currently on the Base blockchain, the MEVFrontier USDC Vault gives supply rates at 14%.
That number seemed oddly high, so I looked at the market exposure of the vault, and it is exposed to the satUSD/USDC borrow vault.

In that satUSD/USDC vault, the borrow rate is currently at 522%, with 0$ liquidity. Quite strange, so I looked at the borrowers and found this guy (0xfdB4e1192284bfc94E55B5934A97b67337a92aa6), that borrowed 46,490 USDC with a 100k satUSD collateral. His borrow rate is currently at 535%.

What's even the point in doing this ? satUSD seems like it's yet another stablecoin (didn't know about it), but it looks quite stable for some time now so bad debt seems out of the scope.
Could someone smarter than me explain the strategy in this ? Won't this guy get liquidated quite soon ? Ain't nowhere in the DeFi space where you could counterbalance that borrow rate with USDC.

Thanks and Stay safe everyone !
