Question on impact of modifying CDT on a process model that uses them

As per our Appian documentation,
If we do modification to a CDT,(without closing the referencing process models),the changes made to the CDT won't be reflected automatically in the referenced process models.But in my case,I have updated a CDT where my process model is in editing mode.However after saving the changes in the CDT when I closed and opened my process model again, I noticed that the CDT has been updated automatically.I'm working in 16.2 version. Is there any enhancement on CDT updates?
