There was this article in the newspaper about an arborist team (3 guys) doing some work about 10 minutes away from where I live, it was pretty cool with an article about something else than usual.
He's quoted; "this saw is dangerous because it's so lightweight and quick".
I'm guessing they are talking about top handle saws in general....just being light weight, highly maneuverable, and semi-more dangerous than rear handle models....not sure I necessarily agree, but that's my guess.
