Is it just me or are the hydra changes out of whack?

Titanic Hydra Total cost increased to 3440 from 3300 Can now be exchanged with Ravenous Hydra for free.

I can't tell if this is just a typo or if you can trade titanic hydra; a 3440g item for Ravenous hydra; a 3600g item. I mean that's 180g handed to you freely.
