LS_DRV and Q2 interaction

I'm wondering why Q2 gate is connected to LS_DRV signal. I'd have understood if it was connected to a STM32 GPIO as a way to prevent current flowing in reverse from the battery to the solar panel.

In the current schematic, in normal operating conditions, wouldn't Q2 enable/disable with LS_DRV, thus preventing some current to flow from the solar panel when "charging" the inductor and, as such, reducing the efficiency of the DC/DC buck stage and reducing Q2 life expectancy ?
