Then we switched to English and spoke mostly in complete sentences. I have a very vague memory of a few of the words, but the chronology here is based largely on what our parents told us by the time we were five or six.
I've sometimes wondered if there are similar cases like this involving other twins, or triplets, etc.

This is a fairly well-researched topic, even! Twin languages (iirc there's a technical term too) are not exceedingly common, but not super-uncommon.
