If you copy and paste code irrespective of bracket position, you will have the same problems. It turns out not to be an issue.
A big positive of using indentation is that it enforces a visual indication of scope vs. languages where culturally it is normal to find code with lots of giant one-liners and braces on one line.
But overall, you just get used to it and don't notice it. Everyone who yells about languages that use indentation is bikeshedding in the worst way.
