Multi-DB install guide question

An easy question, but I just want to double check.

The usage guide says the following:

Line 25: Provide the same name you assigned for your global database in Step 2. example ‘dbname_global’

If I check line 25 I see
add_global_table('something');

It feels strange to add the name of the created global database (wpms_global). The setting is about global TABLE?

Do I just put in my global database name in and that's it.

add_global_table('wpms_global');

I know that the guide says this, but just want to check before running it.

Cheers,
Pieter
