YouTube uses both <OBJECT> and <EMBED> for their embeddable snippet. Why?

Hey all,

Check out this page, then the upper-right box with the embeddable snippet: YouTube - Justice - D.A.N.C.E (Version Finale)

Notice how YouTube has the <EMBED> placed inside the <OBJECT>? Why did they do that? Is it more beneficial?


<object width="425" height="355">
   <param name="movie" value=""></param>
   <param name="wmode" value="transparent"></param>
   <embed src="" type="application/x-shockwave-flash" wmode="transparent" width="425" height="355"></embed>

Right now on my site, I just have the <EMBED> for the snippet. Example can be seen here: Joke example

Any guidance or advice is greatly appreciated! :party:
