I haven't viewed the entire half time show (I'm not a football fan and and old episode of Columbo finishes in a few minutes). I suspect there will be a lot of close reading of everything she sang and did, considering the times in which we live.

In the critical sense, she passed a text (the song) over an event, and even if the entire song wasn't performed, it is, as the article notes, a "dog whistle" for many viewers.
