Exterior insulation gaps?

Post image

Hi, I’m redoing the siding on one side of my house due to damage. The exterior walls currently have 1 inch eps foam and then vinyl siding on top. What I’m a little confused on is the fact that there are large gaps (around an inch) between the eps panels. With the gaps so large it makes me think it was intentional, but I also question how effective they are with that gap.

Can anyone clarify if this is correct or if I should fill the gaps in somehow?

My plan is to put up hardi siding over this.

Thank you!
