Thanks much.

I don't understand the first part:

"With the 10mm reinstalled and tight HERE loosen the 8mm bolt, it will get loose and then tight again. Keep pushing through that and it will pull the crank off, the bolt is pushing against that 10mm cap to remove the crank."

1. Isn't there a comma missing at HERE, ie. "With…, loosen"?
2. After screwing the 8mm bolt and the 10mm cap on top of it back into place, how do I loosen the 8mm bolt since it's now covered again by the 10mm cap?

Incidently, the BB is indeed held by two Allen bolts at the bottom (please ignore the labels):
