It's a little confusing, but the difference is that the "contextual
selector" is a second argument, whereas the "or selector" is a comma
within a single argument. So, if we forget about "this" for a moment:
$('.myclass, #myid')
-- matches all elements that have a class of "myclass" or id="myid"
-- both selectors are contained within the same argument (i.e. the
same set of quotation marks)
$('.myclass', '#myid')
-- matches all elements that have a class of "myclass" and are
descendants of an element with id="myid"
-- two arguments.
One way to include "this" in the selection would be to use .add(). For
example:
$(this).add('div');
-- select this and all div elements.
Hope that helps.

I know Karl's answer is correct, but from the docs (
http://docs.jquery.com/Selectors/multiple#selector1selector2selectorN
) I would've thought the comma meant "select all div elements, and
this".
Is there any documentation that would help me understand this?

Whatever "this" is in that case, it's the context to look for any
<div> (jQuery will only select <div>'s that are ancestors of
"this" in
the DOM tree)
Correction: for $('div',this), jQuery will only select <divs>s that
are descendants of "this" in the DOM tree.
