Because analysing network traffic wouldn’t allow an adversary to see what you’re sending with Signal, but they could still tell you’re sendig a secure message.
What the Guardian is doing is hiding that secure chat traffic inside the Guardian app, so packet sniffing would only show you’re accessing news.

Here’s a relevant stack exchange question. Regarding what an ISP can learn. Of note, everybody is ceding that the ISP can tell you’re using signal, and they’ve moved on to whether or not they’d be able to fingerprint your usage patterns.

Again, not my specialty, but signals end to end encryption is akin to sealing a letter. Nobody but the sender and the recipient can open that letter.
But you still gotta send it through the mail. That’s the network traffic analysis that can be used.
Here’s an example of why that could be bad.
