The linked article says only Chrome on Android supports this so far. As I understood it, other browsers do not show the original URL yet but if they start supporting AMP Real, they will start “lying” too. I say “lie” because while the cryptographic signature gives Google/browsers authorization to display the original URL, the original domain is not involved in serving the request for each user. The original domain could be down or change the content while AMP Real URL cache will still show old data. Copy pasting the URL in a new tab will show different data - from the original domain. Same URL should not show different data between two tabs. I understand cached data can always be stale but hitting refresh in tab 1 vs 2 will show two different but consistent things. That is weird.
