In short, this is the preferred method in order to boost your chances of standing out to agencies through your headshot. Prior to the creation of the camera, portraits were done in vertical format. As technology rapidly expands we must follow this trend. The new format of our electronic devices, such as wider screens, has become the new appeal and when a face appears on one of them; it is presented in a horizontal format. I like to take advantage of this opportunity & to use these formats for your headshot as a general guideline.
