There was a problem hiding this comment.
update the cargo.toml dependency from
anchor-lang = { git = "https://github.com/coral-xyz/anchor", branch = "master",features = ["interface-instructions"] }
anchor-spl = { git = "https://github.com/coral-xyz/anchor", branch = "master" }
back to
anchor-lang = { version = "0.30.0", features = ["interface-instructions"] }
anchor-spl = "0.30.0"
looks good and learned that TransferHookAccount state existed!

This check checks the source token account if it is currently transferring to make sure that the transfer hook can only be called during a transfer.
This is to make sure that for example a counter or similar can not be manipulated by calling the transfer hook directly.
