Is it a good practice to place an assertion in the afterEach block?

Environment: Protractor, jasmine, typescript

I have several tests that have different setup and the same assertion. Is it a good practice to enter different steps in each it inside a describe and the expect assertion in the afterEach block?

Example: Form contains phoneNumberField and a submitBtn;

Test 1: Enter too short number into phoneNumberField => Expect submitBtn to be disabled.

Test 2: Enter text into phoneNumberField => Expect submitBtn to be disabled Example code:

describe('Invalid phone number => submitBtn disabled', () => {

    afterEach(() => {
        expect(submitBtn.isEnabled()).toBeFalsy();
    });

    it('Too short number input', () => {
        phoneNumberField.sendKeys('012');
    });

    it('Text input', () => {
        phoneNumberField.sendKeys('asdf');
    });
});

Honestly I'm surprised it works this way... I was going to say "no, it's not a good practice..." but I didn't find any disadvantages of doing it this way after playing around for a few minutes with it.

But still I wouldn't do it, because if you place expect() in it() blocks, it's easy to see the sequence of the logic in your tests (e.g. open page->expect smtng; click button->expect smtng; etc)

But you can just implement it, use it for a bit and see if it works out well for yourself

P.S. just to visualize why I think it's not a terrible idea as it may seem to be: having below code

beforeAll(async () => {expect(true).toBe(false)});

it("1", async () => {
});

it("2", async () => {
});

it("3", async () => {
});

will produce following output

As it can be seen report is being printed normally where every failure is shown as individual a failure of it() test case
