The L298N datasheet says:

The sense resistor, not of a wire wound type, must be grounded near the negative pole of Vs that must be near the GND pin of the I.C.

design layout example why not in common GND plane? If I connect resistors to the common ground, how does this affect the operation of the device? Thx.

The L289 datasheet Application Instructions - Suggestions, on page 7, says:

The sense resistor, not of a wire wound type, must be grounded near the negative pole of Vs that must be near the GND pin of the I.C.

This ensures that the voltage measured on the sense inputs is all due to the current on that output and not any other currents running through the ground plane causing small additional voltage lifts which would cause errors in the current control.
