Updating Phase in Composing Components

I am taking a Masterting React course and I have just cover the Lecture 17 under Composing components module. I am coding along with Mosh for the counter application. In the lecture - Updating Phase, Mosh shows the prevProps value for counter 1 is 4 but at my end it shows 5 as the (updated one) value .
So How is it different?

Can anyone sort this out?
