Problem of PCB layout  of  ADA4899-1

Hi all,

  It is suggested  in the datasheet of ADA4899 that all ground and power planes under the pins of the ADA4899-1 should be cleared of copper to prevent the formation of parasitic capacitance between the input pins to ground and the output pins to ground. But  if  the copper is removed  , how can the exposed paddle  soldered  to ground ?
