Successfully binded one Mi account into Mi unlock status for two redmi (garnet) phones. will there will be error after 72 hours?

Hello, I managed and successfully binded my same Mi account into Mi unlock status for two redmi (garnet) phones.
Can it be unlock together and running on different PC? Thank you!
will there will be error after 72 hours? Because when I checked through Mi Unlock app for both phones, it indicated as unlock after "72 hours".
Please advise.
Thank you
