This indeed makes it much more clear. The last sentence is exactly the same as 
the second one, so I guess it can safely be left out ;)

Hmm... I'm not sure about "dynamically display other controls". Does that mean 
that controls which are only relevant if a certain feature is activated should 
be greyed out in the deactivated case instead of hidden?
In that case, I'd add: 
"If certain controls in a configuration dialog are only relevant if a certain 
checkbox is checked (i.e. they are dependent controls), disable them instead 
of hiding them if that checkbox is unchecked."
to make clear what should be done instead.

+1 on all the others.

Thanks for improving this HIG!
