Yes - you are right.
I have now done a whole series of tests, where I created nodes in different configurations, and read the debug information.
It is not the present() is I was thinking, that creates the node in the controller. At the Domoticz forum, gizmocuz said that it does not matter what comes first - present() or sendSketchInfo().
So the issue about creating nodes in a consistent way are not related to this. So far so good...
Last evening I tried the stable version 1.5.4. I created ten 100% identical nodes i an row, without any errors. It could be that there are still some issues with the v2 development version, or that the new version are handled differently, and that is not implemented in Domoticz yet.
It seems that I have to go with 1.5.4 for now, and wait until v.2 are released and these issues are sorted out between MySensors and Domoticz.
Thanks for the feedback!
