The image plane can move on its standard or the lens can also move on its standard, it's not limited to the image plane (or sensor, as you have here). Furthermore, limiting the depth of field via a tilt is generally a poor/overused effect related to the optics the lens and/or image plane. Tilts can be used to actually achieve more depth of field. Here's an article with practical examples!

Sorry to be that guy but pedantry warning:
