I suppose we could fire resize on initial load as well. I guess it depends
on what code that uses this looks like. Is the initial size change the
same kind of code as resizing, or is it different code? (e.g. will one set
up elements to frame the video while the other just changes their size?)

The non-normative note there isn't strictly true; the events can't
actually fire until the whole task has finished. It's like the note in the
next step, which doesn't mention that the event in question fires later.
Notes often trade precision for brevity; if they were as precise as the
normative text, they'd be as long as the normative text and wouldn't help. :-)
