Well, that would extract a lot of things like membranes and proteins and such wouldn't it?
Your DNA would likely be in there, but this doesn't sound like any way to purify it or anything.
Indeed, membranes and proteins would also be extracted. However, the procedure described by Dead Parrot does not claim to purify the DNA, merely to visualize it. And it does so because at the interphase between the salt water and the alcohol DNA becomes insouble and precipitates as stringy white clumps.
