Postback doesn't fire when radiobutton is defaulted to checked

This was really strange behavior. I am using an UpdatePanel to trigger a partial postback, and by just setting Checked to true the RadioButton would not trigger a postback. I ended up moving the RadioButtons inside the UpdatePanel, and this fixed the problem.

Is there a logical explanation for this or is this a "feature" (bug)?
