Overcollateralised v Undercollateralised

This is the BIGGEST misunderstanding I have seen amongst the community over the live streams on @Maple . So much so, it is also a staple question on our Quiz Night.

Overcollateralised:
$150m $BTC
collateral for a $100m loan

Undercollateralised:
$100m $BTC
collateral for a $150m loan

Maple is ALWAYS overcollateralised.
