When Catholics say that they pray to the saints they are using the legitimate meaning of making a request, i.e. for the saints to pray to God for us. To suggest that Catholics mean anything else is to bear false witness.
Then there are a lot of Catholics bearing false witness. I'm sorry, but historically Catholic prayer to saints has been presented as prayer to dead saints for the saints personally to intervene in the world. I get that it can be reformulated to a more scripturally sound basis. But the article in question seems to be presenting prayer to saints for saintly intervention as a valid and scripturally supported practice.
