on this page
https://www.drupal.org/docs/7/api/theme-api/overview

the 2 code samples at the top show 2 different ways to use theme api

in the second one the name of the theme being use (form, pager ect) appears twice
both as the name of the array ( $build['table'] ) and as one of the key value pairs stored by this array (array(
'#theme' => 'table', ..... );)

why is it necessary to mention the fact that it is a table twice?

also, does the theme API work the same in D8

D8 theming is completely different from D7 theming.

D8 theming uses the twig framework:

Learn by reading the documentation and by studying existing code from a good D8 theme, like the following:

(download the D8 theme for study)
https://www.drupal.org/project/showcase_lite

(get full theme site distribution from github for study)

I was not talking about themes

I was talking about the theme API
I believed these to be different things.

Themes are like templates with a combination of static html, regions (or twig tags in D8) and various variables drupal provides.
theme API can be used to make a range of front end objects such as forms. these would be inserted into a region.

my question only concerned theme API

The answer to your question involves interconnected concepts, how the D8 theme APIs interact with a theme and/or forms.

The link below is to the theme API section of the Drupal 8 APIs documentation, which you could easily have located yourself.

Drupal 8 theme APIs api.drupal.org

As noted in my prior responses, you also need to learn the twig framework, which involves another API and language.

To understand the above, as I suggested, you should study the excellent example Drupal 8 theme I linked to, to see how all the foregoing works within a theme implementation, and how various forms would interact with a theme using the them APIs and other interfaces. There are many components to a Drupal 8 theme, all of which require understanding multiple APIs and languages including but not limited to:

php
twig
css
html
yaml

about which a thorough knowledge is needed to properly utilize the Theme APIs to interact with the architecture.
