No, in my case it is definitely the part access=agricultural. Maybe it 
has something to do with the delete access action.

But I have looked into the =* code and haven't understood how it is 
intended to work.
One the one hand it is converted to an exists operator.
One the other hand, if I do a way.toString() then I get for example
WAY: 28337476 null(48.02754878997803/11.391620635986328) 
[highway=track,highway=*,width=4,width=*,source=survey,source=*,access=agricultural,access=*,surface=gravel,surface=*,tracktype=grade3,tracktype=*]

Looks like every tag gets an doubled entry with =* for further comparing.

Both solutions could work, but which one is intended??
