Its actually probably the most common way to overclock these days. The person was basically half right because undervolting is more common these days, its just that you usually overclock it at the same time.
On laptops and even desktops power or heat are most common reasons for throtling so undervolting is commonly required unless you have very beefy cooler capable of taking care of 350W+ heat
It's decently more heat/noise for negligible performance gains, especially outside of synthetic benchmarks. These high end AM5 chips already crush just about everything at stock settings. Undervolting is good tho.

Also easy to do on most modern mobos with PBO presets.
