I thought so too initially, then I changed my mind and I like it the way it is. The reason being is that describing the intent allows changing the implementation and keeping the meaning. It is the intent that matters to the administrator not the implementation.

Also worth noting that is the fact that the use of WR_INDIRECT log writes is altered depending on this property. Even in a pool with no dedicated log devices, changing this property can have an effect on overall performance, so it clearly cannot be defined as simply as "use log devices" or not.
