How do you use Alrik's Sword to train 2H cheaper?

I'll quote this from Ellusion's amazing FAQ on GameFAQs:

"Since
training a particular weapon skill doesn't involve you wielding the weapon in
question, two-handed fighters can train while having Alrik's sword equipped to
superfically raise their competence level to another level, thus making it more
efficient to train two-handed skill. Example: train two-handed to 34%, then
equip Alrik's sword and now train one-handed with 10LP bring you to 30% (10%
base, +10% from Alrik's Sword, +10% from 10LP) and competence level 'fighter' in
both skills. Now, with Alrik's sword still equipped, continue training two-
handed now at normal cost, up to 64%. Read the Double Blocks book, then remove
Alrik's sword and bring out your favourite two-handed orc slicer - you'll now be
a rookie 20% one-hander, but a Master 69% two-hander, with only 10LP 'wasted'. "

I get the idea behind this, but I must be confused about the math. If you have 2H at 34% and 1H at 30% (using the above trick), that would cost a total of 40 LP, right? (10 for 1H and 30 for 2H)

But why bother to train 1H to 30% manually, like it suggests? Wouldn't it still cost 40 LP to just leave it at 20% (10% base and 10% from the sword) and then just train 2H from 34% to 64% all at once?

Or am I doing the math wrong?

I also just read in N3Burgener's FAQ that with NOTR you no longer learn 1H and 2H simultaneously. Does this mean the above trick no longer works?
