American Express Membership Rewards - FHR Upgrades listed on Website?

I was cruising the AMEX FHR website for a possible upcoming stay in NYC... I saw something under the RC Battery Park that I hadn't seen before.. I also checked some other hotels and didn't see anything like this listed ...

this is for a Deluxe room
This room has an option to connect to an Executive Deluxe Suite. If an upgrade is available from this room it would be to a Statue of Liberty View Room.
and for a Statue of Liberty View Room
At 425 sq. ft. this room features a bedroom with panoramic views of the NY Harbor Ellis Island and the Statue of Liberty. This room connects to Statue of Liberty Rooms, Executive Suites, The Liberty Suite and The Ritz-Carlton Suite. If an upgrade is available for this room it would be to a Club Statue of Liberty View Room with Club Lounge access for 2 people.

The other room types don't list the upgrade if available option.. I've seen threads referencing the upgrade possibilities available to FHR, which the agent can see but I've never seen anything like this listed on the website.. has anyone seen this for other hotels?

FDW

what it connects to as well, interesting

i might explore this at some point

i would tend to assume they are not going to put all this data online, as it would be an insane amount of entry, but we can always hope

although back when they had the other sites for non-US cardholders to book online, i posted about some upgrades being specified. as i recall, DrivingRain said they were told something different from CTS when asking about highest possible at LMO, compared to what i was seeing. i think i was looking at the one for germany, possibly with cent benefits.

(and indeed agents can "check contract" for upgrades)
