The reason I can think of off the top of my head is because _myInt shows up at the top of the intellisense context menu.
I don't think accessing _myInt violates the spirit of encapsulation at all; it's a private member field of a class. Any code within the class SHOULD use the _myInt. It's private, after all.
The only thing that matters to the outside world is the public contract of the class. _myInt is a concern of the class itself, not part of the public facing contract.
And like I said - it's easier to grab _myInt with intellisense when you're coding.
