In that case, unless there is a functional problem, I wouldn’t worry about it. If you just connected a couple of chips on the bench it would look a lot cleaner. 1-wire is designed to work well with less than optimum conditions/cheap wiring/external noise. The bus doesn’t have to be zero volts for the chips to recognize a logical zero, on the 1-wire data sheets I looked at it is specified as anything below 0.8 volts.
