No, that's not how CSS 2.1 uses the term. About "Applies to":

"This part lists the elements to which the property applies. All elements  
are considered to have all properties, but some properties have no  
rendering effect on some types of elements." [1]

So an element with display: table-row-group "has" the list-style-position  
property, but the property does not apply. An assert that reads "The  
'list-style-position' property applies to elements with 'display' set to  
'table-row-group'." is at odds with the spec.

I can't figure out what this is supposed to say. If a property does not  
apply to an element that simply means that the property has "no rendering  
effect"[1] on that element. Do you have an example that shows a "reset"?
