What the primary record establishes

ERC-7575 extends the ERC-4626 model so several asset-specific vaults can share a token representing ownership shares. The vault reports the share token address through share(), which can be distinct from the vault address. Ethereum ERC-7575 ↗

What the distinction changes

Suppose one vault accepts USDC and another DAI, and both use share token S. An application sends a deposit request to the selected vault and reads the share balance from S. Treating the vault address as the share address can produce an empty balance or a failed call.

What to check before drawing a conclusion

For an exit, quote the intended asset and vault, check the permitted amount and preview the operation. A common share token does not guarantee immediate liquidity in every asset. Test the integration with distinct addresses for each vault and the token.
