The halt is the reaction. The news came first.
A H11 tells you the exchange stopped the tape. It does not tell you what was said.
By the time a symbol appears on this page, the thing that moved it has already crossed a wire somewhere. If you want to be reading the release rather than the halt notice, you need a feed measured in seconds, not refresh cycles.
