How come that excuting plantUML with -checkonly option generates images?

Hello!

After generating automatically some diagrams using clang-uml, I want to check the syntax of generated .md files that contains @startuml and @enduml using plantuml -checkonly

The thing is that this is very time consuming because all images are generated but I do not understand why as the help command prompts that -checkonly option should not generate the images. Have I not understand how it should work? Do I have to use another option conjointly? Is it bugged?

Thank you
