Incrementing a Variable when multiple users are accessing the MS Flow

[johnjohn123]

I have the following condition inside my MS Flow:-

where mainly i have 2 variables:-

1) TotalNumberOfUsers

2) NumberOfUsersWhoApproved

and as shown above i am incrementing the 2 variables by 1. but my question is let say multiple users access the condition at the exact same time, then how will MS Flow handle this? let say the variable current value =3 , and 2 users access the MS Flow at the exact same time, then can the Increment only increment the variable by 1 instead of 2 for the 2 users? or MS Flow is able to handle this situation? if not , then how i can handle this?
