DRV8847: Datasheet question asking

Hi team,

My customer has a question about datasheet., please see below question.

1.) Check DRV8847 datasheet MODE pin if Hi-Z is independent bridge interface. The schematic diagram of the independent bridge interface circuit in the datasheet shows that ISEN12 / ISEN34 do not connect Rsense in series but directly connect to GND, Therefore, it is a bit confuse. Is it still necessary to adjust the current in series with Rsense when applied to an independent bridge interface?
