How is it possible that a token has the same price with four LP in different blockchains?

I have this existential doubt and I didn't know where to put it. ¨
I hope it is in the right space.

We have a token like Axies Infinity per example.
In which we verify that it have contracts deployed in several blockchains and ethereum too.

How is it possible that they have the same price if in each blockchain there will be different liquidity pools with different buying and selling markets in volume?
