Total yield on Binance liquid swaps

Can someone explain the concept of “total yield” on Binance liquid swaps?

If for example I provide liquidity to the pool POND/BUSD that currently offers total yield of 44.68%, is this yield “guaranteed” into perpetuity (meaning so long as I do not redeem the tokens from the pool)?

I understand that the yield changes based on supply and demand, and that for those who will provide liquidity at a later date it can be higher or lower than 44.68%. But what I am not clear about is whether the pool continues to provide 44.68% total yield for those who provided liquidity when that specific quote was in effect.

It seems “too good to be true”. Yes, there are risks around impermanent loss and other issues. But these risks seem to be focused around loss of upside as opposed to downside risk (is that correct?). But what I really want to understand is whether it is possible to “lock” the quoted total yield
