That's what they seem to be hinting at.

They've also mentioned that has something in common with both Anivia and Cho'Gath. My guess is, his abilities (or possibly his passive) will give him a passive stat gain of some sort for killing things - much like Cho's feast - possibly causing him to evolve from ooze blob form to the bipedal clawed form you can see in the second page of the research journal in the process.

However, killing him while he's in man-mode only causes his core, the ooze-ball, to pop out and allow him to run away - basically offering him a second chance at life like Anivia's egg timer. He'd lose some of the stat gain he'd got from being in man-mode, but all he has to do is farm the jungle a bit to get back to what he was...

At least, that's my (semi-)educated guess.
