Can you point to where it says that in the report? It actually says:

an IME will commonly reach out over the network to a cloud-based service for suggestions if suitable suggestions are not available in the input method’s local database.

So it doesn't send "every key typed".

Until you realized what sequence of letters most commonly not have any suggestion. That's right, when you type your password.

Literally says in bold even:

the keystrokes of Sogou Input Method users can be decrypted by a network eavesdropper, informing the eavesdropper of what users are typing as they type.

AKA every keystroke

I assume they mean "if suitable suggestions are not available in the input method’s local database". Like you start typing a word, and when it doesn't find any match locally, it goes to the server. After that, any additional keystroke gets reported to the server "as they type".
