What is a P1349-VT Code versus a P0300 -Random code on 1999 Lexus ES300

My mechanic knew that there was a pending code of P0300 yet did other work of about $350.00 before fixing the original code? Would it have been easier and more cost effective to fix both Camshaft Solenoid at the same time then to do them serpartely?
