AD8130 definition of terms

I name v1 = instanteneous voltage of pin 1 versus ground

           v8 = instanteneous voltage of pin 8 versus ground

suppose that always v1 > v8 > 0

suppose AD8130 works with supply voltage +12 and -12 V

following the specs (page 7) : common mode range : plus or minus 10,5 V and differential operating range : plus or minus 2,5 V

These are my questons :

1)do you mean : -10,5 < (v1+v8)/2 < +10,5  and -2,5 < (v1-v8)/2 < +2,5     and v1 < Vsupply =12

2)or do you mean v8 < 10,5 and v1-v8 < 2,5 and  v1 < Vsupply =12

Thank You.
