Documentation of discriminator custom _id field text doesn't match example

What is the current behavior?
The text describing the behavior of cust _id fields doesn't match the example. The text says:

You can work around this by setting the _id option to false in the discriminator schema as shown below.

But the example does demonstrate this workaround, it simply shows how the custom _id on the base schema overrides the discriminator schema.

If the current behavior is a bug, please provide the steps to reproduce.

Review of the documentation at https://mongoosejs.com/docs/discriminators.html#handling-custom-_id-fields

What is the expected behavior?
The example should demonstrate the text, i.e., show how overriding the discriminator _id can be worked around.

What are the versions of Node.js, Mongoose and MongoDB you are using? Note that "latest" is not a version.
Node.js - 13.8.0
Mongoose - 5.8.12
MongoDB - 4.2.3.
