Corridor - Risk vs Volatility

In the CFAI books, it states if an asset has high volatility, you want narrower corridors because it’s more likely to go even further away from your desired mix.

However, in one of the Topic Tests, it states that an asset with high risk should have wider corridors.

Can anyone help reconcile these? Risk and volatility are essentially synonymous for our purposes, so why is this different?

In the CFAI books it refers to risk tolerance of the investor being positively correlated with corridor width. Do you have more detail on the topic test question/answer?
