Will the passwords on a new device in sync chain will merge with existing passwords?

HI, This is my first time asking question regarding the sync feature in brave :slight_smile: . Please Bear with my English :grin: . Now to the problem!

I have 2 devices : Window 1 and Window 2.
On window 1 i have already started sync chain with android and i have saved many passwords . Now, i have new laptop (window 2) but i didn’t connected sync chain yet and started saving passwords on window 2. Later i thought of starting sync chain on my new laptop (i.e. window 2) . BUT! I am confused! if i start sync chain now ,will it merge with already existing passwords of window 1 or will the sync overwrite window 2 passwords ??
Thanks for your time :love_you_gesture:
