History.txt - Calling for names in the construction file

[Rexxx]

From the history.txt:
v 1.61
The Default_Ai_Construction_Vehicles.txt file will now allow for the design name or the design type. The term "Colonizer" is till hard-coded to be evaluated to the needed type of colonizer .
When looking for the design to build, the game will look for the latest design which matches the design name. If no match is found, then the latest design which matches the design type will be located. If neither is found, this purchase item will be skipped.

What does the second sentence actually mean? I can translate it into German but that doesn't help much.
