LTC4066 terminate charge cycle

Why does the LTC4066-1 ONLY stop charging when timer expires, and NOT when CC/10 is below a certain threshold ?

(We now see that the LED is switched off, but charge current is still flowing into the Li-Ion cells, until the timer expires)

Is there a good reason to do so ?

Is there a similar device which stops charge cycle at CC/10 threshold ?

Thanks for your reply,

WKR,

Eric C.
