Does MVC remember checkbox values after submit?

I'm a php head and getting to grips with ASP.NET MVC 5. In php, after submitting checkbox fields, in order to post back the form with the checkboxes you checked initially set to true, you have to run a if isset on em.

However reading up on model binding in mvc, it seems that this is done automatically for you, i.e checkboxes are returned after form submit checked, if originally selected, using either the HTML.CheckBox or HTML.CheckBoxFor helpers.

Is this the case, or am I expecting too much of MVC?
