Actually, yes. The reason that they look so different is because of where the damage was and how the structure failed. WTC 7 looks more like a conventional implosive demolition because of how it failed - it's much more similar to what we're familiar with when we see buildings purposely imploded on TV. The structure failed at the bottom where there was a major load transfer truss between the newer WTC7 structure and the sub-station it was built over. When the support there went, gravity pulled the rest of the building down, from the inside-out. Of course, there are differences: the debris field wasn't nearly as carefully placed as you would like in a demo; also there were no visible or audible explosions from cutting charges.
I say looks like a CD, because that's the only way to describe it in figurative language. We don't have any other similar thing to which to compare it. But it's still just a figure of speech - a comparison - in this case, a simile. It's not literal. For instance, if I was trying to describe a Boeing 757 to you, I might say that it looked like a DC-10. That doesn't mean that I think that it IS a DC-10, I'm just using comparative language that I hope you can relate to to describe it. And, to someone who isn't an expert at identifying different types of planes, that's a pretty valid comparison.
To someone who is an expert, my comparison may seem innacurate because they're aware of the more nuanced differences between the two. I think that's the root of your misunderstanding.
