To me, making a bus journey means getting on the bus, riding the bus

TfL does not share your interpretation.

If you touch in on the second bus within one hour of touching in on the
first bus, you are not charged and the journey can be completed in
whatever amount of time it takes.

Is this documented somewhere?

It's not in the TfL Conditions of Carriage (12 Sep 2016). Section 6.8.6 says "If you make a journey using pay as you go on a bus or tram, you can make a second bus or tram journey for free within one hour of first touching in." As has been noted already, that is ambiguous.

As others have said the system works solely, on buses and trams, on when you touch in. Provided the second touch in is within the advertised 60 [1] minutes you will not be charged. While I understand your query about the written language used the Oyster system is using a long established feature that allowed for through tram to bus tickets in the New Addington area. This is why the "Hopper ticket" was launched so quickly after Mr Khan became Mayor - it was just a case of entering different modal info into the system.

The more complex "unlimited bus/tram rides within 1 hour" and "get second bus ride free after a tube/DLR/Train/Overground journey if within 1 hour" functionality is new and is planned for introduction in "early 2018" which I assume means the January Fares Revision. I also assume TfL are sufficiently confident in the software changes that they are testing it now (or will after the Sept fares revision [2]) before having to freeze system changes to allow for the main Jan Fares revision (Travelcard and NR price changes).

[1] in reality the system parameter is 70 mins but TfL don't advertise this.. It gives a little bit of "flex" in case the second bus runs late and also covers where services run at 30 min headways and may not always run precisely to time.
[2] yes there is a Sept fares change. It usually affects fares to / from Watford Junction plus some other minor tweaks by the TOCs.

Thanks, Paul. Interesting information, as always from you.
