Not completely true, that's the purpose of "Pending" diagnostic codes. A scan tool can pull pending codes for intermittent faults, such as an intermittent MAF sensor, which I've personally experienced.
True that even after cleaning it, it could still be bad. The better test for the MAF at this point would be to use a scan tool in datastream mode to monitor air flow as reported by the MAF, and while doing so, also monitor bank 1 and bank 2 lean/rich status along with the fuel trim values.
