Please don't forget that there isn't a single UK-wide or England-wide police force. There are many small regional forces across England. Quite often they issue advice that's dumb. You'll see a police force's social media team retweeting a "scam alert" that's an obvious hoax.
So, we don't know why they've issued this advice and we don't know if they've based that on sensible factual information of some bit of misinformation.
