Content.pagination Vs show_pagination

Hi there.

In the Quark theme, pagination is defined as a boolean variable twice, once in blog.yaml as content.pagination and once in blog-bits.yaml as show_pagination.

The blog template displays pagination if content.pagination and show_pagination are true. However, if content.pagination is not defined, even if show_pagination is true, the pagination is not displayed.

What is the difference between content.pagination and show_pagination?

Does it make sense to have two variables defined for the same purpose?

Thank you
