red mage limit break question

[Viladin]

Does the red mage limit break get any better?
I.e. last longer 1 round plus 1 round per 4 levels ect.

Redmage
Dual Spellcasting (Su): This Limit Break allows the red mage to cast two spells in the same round. MP must be paid for both spells. This limit break requires only a swift action.

Bluemage
Dual Azure Mastery (Su): This Limit Break allows the blue mage for a duration of 1 round + 1 round per four blue mage levels to cast two blue magic spells a round. MP must be paid for both spells. This limit break requires only a swift action.
Was this an oversight or on purpose?

Oversight. Red Mage's limit break should be the same as Blue Mage's.
