BQ79616EVM-021: GND tied to CELL0 at connector via a thick trace

Part Number: BQ79616EVM-021
Other Parts Discussed in Thread: BQ79616

Tool/software:

Dear Experts,

In the schematic of BQ79616 evaluation board, it said GND tied to CELL0 at connector via a thick trace. 

Two related questions here,

question1: what will happen if GND didn't tied to CELL0? which means in the schematic, R49 is open.

I am guessing there will be risk that VC0 vesus AVSS may be out of spec which may damage BQ79616?

question2: since CELL0 is tied to GND via a think trace which means CELL0 is always GND .

but why in shcematic there are capactitors and resistors between CELL0 and GND. which is no sense to have capacitors and resistor here if CELL0 is GND, right? 

 

 

did I miss anything?

Thank you very much.
