Divine Light - Typo?

[Zitroni]

Is there a typo within the Prayers of the Stormhosts: Divine Light text?

"If you instead chose a friendly unit, enemy units re-roll hit rolls of 6 or more when attacking that unit until your next hero phase."

In the Tools of War part of the rules it is stated:

"Some rules allow you to re-roll a dice roll,
which means you get to roll some or all of
the dice again. You can never re-roll a dice
more than once, and re-rolls happen before
modifiers to the roll (if any) are applied."

So modifiers should not apply to the roll and a 7 or more is not possible. The text implies that positive modifiers to the enemy attacks would make Divine Light even better.

The question was already asked on facebook:

Here is the reply by gw for convenience:

"That will simply be in there for the sake of completeness; it's better to say "6 or more" just in case, one day, in the future, there is a rule that works in a special way to add modifiers before re-rolls are made. It's a good idea to cover all possibilities just in case!"
