DI example doesn't agree with explanatory text

[cropredyHelix]

The first DI example (shown below) doesn't agree with the text above it that references a private constructor.

public class DuplicateAccountBlocker
{
    @testVisible private final AccountsSelector selector;

    public DuplicateAccountBlocker()
    {
        this.selector = new AccountsSelector();
    }

    public DuplicateAccountBlocker(AccountSelector mockSelector)
    {
        this.selector = mockSelector;
    }

    //...

I think you meant the example to look like:

public class DuplicateAccountBlocker
{
    private final AccountsSelector selector;

    public DuplicateAccountBlocker()
    {
        this.selector = new AccountsSelector();
    }

    @TestVisible private DuplicateAccountBlocker(AccountSelector mockSelector)
    {
        this.selector = mockSelector;
    }

    //...
