What's keeping you from having infinite attacks with Gaia Emperor's stride skill on two rearguards with the Engorge ability?

So hear me out

1. Stride over Gaia emperor
2. Use Gaia Emperor's Stride skill to call two Tyranobrute's with the ability to come back to RC when put into the drop zone.
3. Attach with TB 1, eat TB 2, become engorged. TB 2 bounces back Standing.
4. Attack with TB 2, eat TB 1, become engorged. TB 1 bounces at Stand.
5. Repeat steps 3 and 4.
6. Win?

I don't know if I'm missing a ruling or something with this, but from what I can tell this seems legal. If it is, dear god my girlfriend is gonna destroy me with Lazer Dinos.
