I hope this isn't a resolved issue.  I wanted to put my 2 cents in too.  
I think this should be a warning in ERC.  If you are methodology based 
designer, then you likely do not tie local nets together and if you do, 
it was a mistake.  This is the only feature in KiCad that has every 
burned me and the board....  At the very least, if you do this try of 
connections, then you should be reviewing it anyway.
