Maybe they used the QRH which told them not to pressurize the aircraft and land at the nearest suitable airport?
Indeed. Correct. I wonder why Boeing didn't include a light sensed from the tail cartridge to show a compression, or is that an option. It is left to 'suspected' tail strike; and when there's doubt there is no doubt. Of course the pressurisation could indicate normal, but under TEM, climbing to crz and high diff would not be good. (I was thinking of another checklist and became senilely confused)
