One checkmark = message delivered /
Double checkmark = somebody read it. That somebody might as well be WhatApp doing a MITM
The double checkmark stuff the blog talks about just means you cannot retroactively rekey already sent (old) messages.
WhatApp inserting itself as a MITM can however read (and double checkmark) and new messages after they did the MITM rekeying

It is actually slightly different. One checkbox means received by WhatsApp, two checkboxes means received by the recipient and two blue checkboxes means read by the recipient.
