A quick look at openoffice's autocorrect table shows entries like

ahve have
alwyas always
amde made

What makes the error-entries more natural than the correct ones?

I would suggest its an excess of independence required of the correct
ones
If 'da' is LH and 'di' is RH
da di da di
is easier to type fast than
da da di da

In fact da da di da
is probably harder than da da da da

IIUC dvorak's advantage (one of them) is that it aims for a rhythmic
alternation of LH and RH
