BQ77904: 3S to 20S?

Part Number: BQ77904
Other Parts Discussed in Thread: BQ77905

Tool/software:

The datasheet seems to contradict itself in three places.

The title says "3S to 20S". 

Page 1 shows OV/UV thresholds low enough for a 1S pack.

"Overvoltage: 3 V to 4.575 V

Undervoltage: 1.2 V to 3 V"

Datasheet body, section "8.3.10 Configuring 3-S, 4-S, or 5-S Mode":

"The BQ77904 supports 3-S and 4-S packs, while the BQ77905 supports 3-S, 4-S, and 5-S packs."

These three pieces of information seem to contradict each other.
