It does, and another tip is to turn the tyre iron over so that the lip at the end is pointing upwards rather than (tube-pinching) downwards, and giving the iron a smear of tyre soap too.

Hazet tyre levers used to have a notch on the backside of the lever near the tip to engage with the edge of the rim to make it easier to do exactly that

We also have a lever that has been shortened about 10mm on the end to lessen the chances of pinching the tube

As to fitting tyres I tried the "tie wrap" method when putting a new Metzeler on the front wheel of my SR a while ago

I haven't tried it yet because in the time it takes to put the cable ties on I'd normally already have the tyre fitted and pumped up but that's something that come with a lot of practice, next time I do one I'll have to try it to compare

Kickaha,
I tried it with the Metzeler Lazer as they have very stiff sidewalls and more difficult to do than say Avon road riders
My next project has beaded edge tyres which are a bastard to get on *problem* so I am going to try the tie wraps again

I use Melco 6" levers and some Johnson's baby powder for tyre changing. The big mistake is to use huge levers and lots of grunt. A perfect combination for pinching tubes. I am wary of using washing up liquid as some do as it has a high salt content. A good way of starting corrosion on the inside if the rim.
I took an ancient Avon GP tyre off a wheel yesterday (same 6" levers) and found that although the tyre was hard and with circumferential cracking, the tube was in pretty good order. Don't think I'll use it though.

That washing up liquid contains salt is another Net myth. It actually contains "salts" ie a certain type of chemical compound but not necessarily anything to do with the increased risk of corrosion.
The real problem with washing up liquid is that it remains "slippery" for too long inside the tyre/rim, unlike proper tyre soap which disappears very quickly.

I have heard of tales of people using WD40 and finding the tyre slipping round the rim and tearing the valve out. :o :o  Not sure if it's another 'urban myth' or 'Net myth', but tyre soap is the stuff for me.  It's cheapish to buy and lasts forever (in the tub, not on your tyre). *eek* *eek* *beer* *beer*

If you wash your bike with washing up liquid, the alloy dries with tiny but visible corrosion specks, indicative of salt. But salt has always been in common detergents, according to my former colleague who was employed in a detergent factory. Anyway, I prefer the baby powder. It smells better.

A quick scoot around the 'net' seems to indicate that salt is present in many detergent products.  It's already a big no-no to wash paintwork with washing up liquid, especially with modern, water-based paints.  When the bike gets mucky, I use hot water only, then hand clean with WD40 or a bit of meths for really greasy areas.  For thorough cleaning of oily bits prior to reassembling and application of threadlocker, it's carb cleaner.

As for the innertubes, talcum powder is only used on the tube to stop it sticking and rubbing.

It could be indicative that the washing up liquid has very effectively degreased the alloy, allowing  "oxide" corrosion to form instantly?

I use long levers so I don't have to use much grunt, the ones at work are 20 inches, the ones I have at home are about 15 as I find that's about the longest I can comfortably fit in my bike kit to carry with me
