Not really, at least one of those autocompletes worked when I checked earlier and it was soon removed, all it means is that she clicked on them to see who was tweeting it. I'm not a fan of hers at all, but it's not rocket science to realise how Twitter works, you click on something and you've 'searched' for it and an 'x' appears.
or the auto complete came up from everyone responding to her tweat and searching it?
