Inherent implication isn't the point. How do people fluent in a language use it to communicate?
If heos does not inherently imply resumed normal behavior after the terminus, neither does it imply the continuance of the exceptional behavior afterwards. If you are going to rigidly follow dictionary meanings and grammatical rules, then you have to say, "We don't know whether or not Mary and Joseph enjoyed normal marital relations."
Matthew isn’t indicating Joseph and Mary had marital relations after Jesus’s birth but the status of Jesus’s origin and Joseph’s role. Heos marks the period before the birth because that is where the paternity issue is relevant. As you’ve acknowledged, heos does not inherently imply either reversal or continuation, which means Matthew 1:25 does not speak to what happened afterward. Any conclusion about later intercourse is supplied by the reader, not by the Greek text.
