I think they are saying:

"If your derived work has UIs, they must display Appropriate Legal 
Notices; however, if the original program has UIs that do not display 
Appropriate Legal Notices, you don't have to modify them to do so if you 
keep those UIs in your derived work."

Thus you cannot remove the notices and you must include them in any NEW 
UIs that you create, but you don't have to retrofit UIs that were part of 
the original work if they are lacking the notices.

"Program" refers to the original, unmodified work under license. "Covered 
work" refers to both the original work and your derived work, though in 
this case it would seem to refer to your derived work.
