LTM4668A output current at burst mode

Hello

LTM4668A datasheet rev.A P.11 says below.

"During Burst Mode operation, the peak current of the inductor is set to approximately 400mA in normal operation
even though the output of the error amplifier (COMP) indicates a lower value."

My understanding is below.

Is it correct ? 

" If LTM4668A is set to burst mode, output curent limit  becomes from TYP 2.0A to 400mA .

 If the load requirement is greater thean 400mA ,  we should select the other mode . "

Maybe,  myunderstanding is incorrect but  I don't understanding  above datsheet description.

Please let me know your advice.

Regards,

Teli
