Мафия 85. Lux in tenebris

I don't quite understand the Hydra mechanic. Let me reiterate. Start: 2 heads. To start eating, it needs to lose a head (a very restrained Hydra on a diet). It loses a head, there was one. It eats a corpse for the first time. It now has 2 heads, and the head limit from an attack is increased.

I don't understand you... Why does the Hydra need to lose a head to start eating? If it lost a head, when did that happen? And finally, if it really did lose a head, it should now have 3 heads (instead of one lost, two new ones grew, thanks to the one point of sustenance it had initially). Isn't that right?
