   Yep. I agree it's not needed, and It certainly works like that, so from 
performance point of view it is 'slightly` better to remove, and I am not at 
all  against removing it, i just want to see if it bothers others from 
"reasoning" point of view. I even initially implemented it without the commit, 
but when I looked at the PR after I pushed it - my internal policeman told me 
"let's make it consistent" and I pushed a changed commit.
   
   But if it's just me who is bothered by that - I am perfectly OK to leave it 
like htat.
