For the sake of simplicity, a finer detail was suppressed. The Merkle tree of Ethereum is not a binary Merkle tree, as we saw for the bitcoin blockchain. You see, binary Merkle trees are great data structures when it comes to authenticating information that is in a list format, that is, a series of data chunks placed one after another. For such a transaction tree, it really doesn't matter how long it takes to edit the tree after it gets created. This is because the transactions remain in a form of one frozen tree which can only keep growing.
