No, it should behave the same, and in that sense you have stumbled upon
I reproduced the error, and I know how to fix it.
I expect to create a PR for that within the day. I still have not
figured out yet why there is a need for a fix, so please bare with me
until I can give you a more complete status report.
In any case it will be fixed in develop and you will be able to use
either one of the point models in discussion.
