How Group works in format rule filter

Summary:

Hi All,

Let say I have some conditions, x=10 and y=20, if both the conditions meet,it will return true, then perform auto-submit and auto-approve.

But when it comes to group, I want to understand how it clubs more than one condition like.

Rule Summary:

Group :( True) [If all the below conditions comes as true)

x=1 and y=2 ----------------------> ( True)

AND Group ----------------------> ( True)[ If all the below condition comes as true]

Balance=100 for functional currency

AND Balance=100 for Reporting currency

AND Balance=100 for Entered currency

AND Group ----------------------> ( True) [ if either of the below conditions comes as true]
