Cutting a live transmission line is incredibly foolish, for many reasons, but I'm guessing the station has a modern(ish) solid state transmitter, which has great foldback protection.I've seen (and personally tested) AM transmitters dead shorting, and within less than a second (probably less than 100ms, but I haven't measured precisely) it will fold back on a dead short to like 1% of its operating power, lower if it still detects a short.
This is to protect the (even more expensive) transmitter from lightning strikes or other weird eventualities (like the line leaking pressurized nitrogen, used to prevent shorts from moisture mainly).
But replacing that 3" transmission line is not cheap or fast. Usually the runs are planned and designed, and every elbow / connection has losses that are accounted for.

I know a guy who works for a major broadcast site company here in the UK, who caught some people up at a remote transmitter site by blocking their pickup in with his van. They admitted they were there to steal copper scrap. He gave them about 100kg of scrap aluminium (decommissioned aerials) that had been subject to the usual "We'll come and get it next week, next week, oh so busy this week, how about next week, maybe the week after?" from the people that were supposed to pick them up.Then he offered to give them a tour of the transmission building.
"See that?" he said, pointing to some nice thick copper cabling, "if you touched that you'd die, instantly. And see that over there? Yeah, if you touch that, you'd die. That stuff there, too, kill you if you even went near it."
Then he pointed out the big polished copper waveguide going up to the main TX stack, think in terms of a thick copper 4" sewer pipe leading out through the building.
"See that, know what would happen if you touched *that*?"
"We'd die?"
"Naaaaaw, of course you wouldn't die! Your arms would vapourise looooong before your heart stopped!"

The article mentions it will cost around $160 per foot to replace, totalling $70k to 100kby Schlagbohrer
