I'll post this here as well:
That's the exact point you need to jump from to get into the SW (it corresponds with a notch in the ceiling which makes the jump possible).
If you jump from there (use the texture on the top of the pillar to align yourself) you don't have to be right on the very edge, in fact you can be some way in and still make the jump.
As for a video of the whole wallcrawl and power bombs thing, well ... er ... there still isn't one. :P
