No, they are indeed talking NL. The events have longer levels and bigger starting stacks based on the buyin size.
The 200$ events are 30min levels, 2k chips
The 300/400$ events are 40min levels, 2k chips
The 500$ events are 50min levels, 3k chips
The 1KME is 50min levels, 4k chips.
In all events the final table levels are 10min longer than whatever the normal levels are.
