Now I don't know the exact details of which governments had which access (was it just for warrants, which nations, what was the line between actual terrorist versus persecuting journalists), but there was absolutely bulk export and the fact that they are lying about it makes me inclined to presume the worst.
The US agency would type in the gmail address of the subject (ie the primary key/identifier) and somewhere between the agency and Google a decision would be automatically made as to whether the owner of the account was a US person* or not.
If yes - FISA warrant was required
If no - the US agency user would have immediate access to the entire google account (think Google Take Out).
In other words, if you were not a US person there was no duty to protect data.
* = US Person is either a US citizen located anywhere in the world or anyone of any nationality who is physically in the US (current interpretation includes visa holders, visitors and even undocumented but that's shifting)
