Same idea. The MKL02 bootloader likely gets programmed using those points.
If you follow the traces on the pcb, they go to pin 14 and 16 from the KL02.
In the picture above:
left test point is pin 16/PTA2/SWD_DIO
right test point is pin 14/PTA0/SWD_CLK
If the KL02 chip is not write protected it can be programmed with the SWD interface. The KL02 chip stores the bootloader, if you program the KL02 with your own code, it'll destroy the bootloader function. It is not recommended to program the KL02 using the SWD interface.
