Confusion about `per` documentation

I am a bit confused by the [documentation of the `per` option](https://github.com/JuliaSIMD/Polyester.jl?tab=readme-ov-file#percores--perthreads):

> The `per` keyword argument can be used to limit the number of Julia threads to be used by a `@batch` block. Specifically, `per=core` will use only `max(num_cores, nthreads())` many of the Julia threads.

My understanding of this is the following:

The `per` keyword argument can be used to limit the number of Julia threads to be used by a `@batch` block. Specifically, `per=core` will use only `min(num_cores, nthreads())` many of the Julia threads.

What is correct?
