Deposit Address is the same for stablecoins on different chains?

Hey everyone, I just have a curiosity about Binance's structure I hope to have answered by someone extra knowledgeable than myself.

I observed at this time that my Binance pockets deposit handle is identical for both USDC on the polygon network and BUSD on the BEP-20 community. How is this attainable? Has binance simply reserved the same handle on each chains so that they seem like the identical handle, however truly do correspond to
totally different chains? Or is it a single pockets handle that's by some means suitable with both chains? After which how is that attainable? I might have expected binance's backend blockchain connection to be as affected by interoperability challenges as the rest of the crypto sphere, until there's something primary I'm overlooking here.

Muchas gracias amigos!
