VDD_SNVS_IN Connection in SABRE Reference Design

Hi all


I want to know the reason why VDD_SNVS_IN connects VSNVS_3V0 and VGEN5_2V8 in SABRE-SDB.


According to the P2 of SDB's schematic, VDD_SNVS_IN  connects both VSNVS_3V0 and VGEN5_2V8 as below.



I think VSNVS_3V0 is enough to operate VDD_SNVS_IN.

Why does the VDD_SNVS_IN connect both VSNVS_3V0 and VGEN5_2V8 ?
