Why would the phishers inform the victim that they got his password? It's against their goals.
Edit: Fascinatingly, the google.com/amp does the redirection, but the google.com is contacted first. Why would google.com do this? Ah, yes... the Google validated AMP cache. Nice.
Edit2: Dude in the reply to this, the fascinating thing is, the google.com is actually contacted from that address first. Mind blown. The phishing using the actual, real google.com. Really, really, nice. That is for me the most fascinating detail from this whole story. It is actually the real www.google.com who made that thing possible. Wow.
