Not sure since when it was changed, but I noticed that I can't push patches if I'm not the author

We must have permissions to do that, this is part of the rebasing part, and I think its fine to fix patches on behalf of someone else.. but its not the best practice for reviewing. 
anyway, please undo this change, unless its something that related only to my env.. let me know

Thanks
