usage-threshold example does not seem correct

The usage-threshold example usage on this page says: --usage-threshold 107374182400

According to the documentation, valid values are: Min 100 GiB, max 100TiB".

The example implies that usage-threshold is the number of bytes, not the number of GiB or TiB.
