Hey, this change isn't really valuable. With the original code it's obvious what's going on. We just want the if to be executed only when the left part of BooleanOr is true.
It'd also be nice to change the line with $dimType instanceof ConstantIntegerType || $dimType instanceof ConstantStringType. I understand that it might be difficult, in that case feel free to close the PR.
