No, it should not. Fallback content should not execute (styling and
scripts), also, fallback content should not be downloaded automatically
(in the given example: "bar" should not download).
However, if <object data=foo> is not supported by the UA, then the
fallback content must execute (styling and scripts), and, obviously, the
"bar" image must be displayed (given UA support for such capabilities).
Last, but not least, the DOM must contain the fallback content as well. In
the above example, <img> must be a child node of the <object> node.
UAs that have no support for the <object> and thus choose to display the
fallback content must also provide the <object> node in the DOM, as the
other UAs which have support. Again, <img> must be a child node of the
<object> node.
HTML5 should eliminate this confusion, by specifically stating the
behaviour in the case of fallback content.
