The reason he gave had to do with the harmonic balancer, being part rubber, shifting over time.

Though there maybe exceptions, most timing marks are on the fixed part of the balancer attached directly to the crankshaft, not the rubber-mounted ring. But regardless, I agree with your mechanic, I've always been a big fan of timing "by ear" though after at chat with Ross Miller about this, the method may not work well on engines with low compression ratios.
