downshifting
That technique is nothing new. It is called power shifting. Welcome to the world of blown engines, clutches, transmissions, broken u-joints and cv-joints. It is going to get expensive, if you continue to do this.
Ok- terminology. Someone needs to put out a definetive document one day. We need standards on this stuff. Or I just need to b!tch slap my pops for my miseducation. I've known power-shifting my whole life as "shifting without using the clutch". I do it on my motorcycles, and when my clutch went on my '86 Golf, I used it for a week to get to and from work, stalling it when I needed to stop, tunring the key in first to start up from a stop. 
I don't do this everyshift. So far just to learn it, then to use it AutoX'n, if I have to shift at all... I guess I really need to start saving my money...
... and everything I read now indicates "blip" means depress-and-hold throttle (until clutch is released).

2. with clutch pedal depressed, gearlever moved from higher gear to neutral
3. throttle blipped
4. with gearlever in neutral, clutch pedal is released
5. clutch pedal depressed a second time
6. lower gear engaged
7. clutch pedal released a second time
What's the point of doing releasing the clutch in step 4 and depressing it again in step 5?
After the throttle blip you can still keep the clutch depressed and move to a lower gear and then release clutch. So there's no point in double clutching. It's redundant.

It's not at all redundant if you're trying to take it easy on your synchromesh cones. It is theoretically redundant on synchromesh-equipped cars, but these are wear items and if you downshift a lot, double (de)clutching will save them.
In the end, I suppose that whether you use this technique or not depends on your level of mechanical sympathy. Or hand/foot coordination
Anyway, mechanical sympathy, that is a great way to put it. I find it exceptionally awkward to perform either heel-toe or double-clutching in my coupe.
I find this all a lot easier to perform with a "hanging" gas pedal, both my 325xi(gone) and my coupe with the floor mounted pedal gave/give me trouble... it is more like you are pushing forward with your heel rather then down, I find myself trying to shift my hips in the seat to get a response from the pedal.

Hi, my name is Thomas, and I am a cronic downshifter with 0 mechanical sympathy. I didn't know, nobody told me it could go this far.

I can straight blip the throttle fine, when I try while heel-toe, I can't get it to go without having to twist myself up so bad I basicly slam the breaks creating an unsafe situation. I went out and was practicing last night until the mall security gaurd told it wasn't a race track and the cops were on their way.
