And that means that there is no current flow through those two resistors right in the middle, because the voltage difference across each of them is zero. This means that, if they were removed from the circuit, it would have no effect on the equivalent resistance.
OK. Understood. Thank you for your explanation!

That's right. But I didn't want to muddy the water by saying nodes could be joined, or elements could be removed, so I restricted my description to just one technique. Either way, I think there won't be much difference in the amount of work involved.

Happily, OP has now had both explained.
