Maybe not...if he's really smooth, and it was a front tire. Certainly possible the guage is off though.
I use 18psi in the front tire of my rigid 29er and weigh 175 in birthday suit. But I'm using a 2.55" wide tire, set up tubeless. And since it's rigid I tend to "ride light" to keep from banging the rims on roots and rocks. I'll occassionally bottom out the rim, but it's really rare. I run low 20's in the rear tire, which is a 2.0"
On my geared HT 29er I use a little more pressure since I tend to charge through stuff vs float over it like I do on the rigid bike.
But like others have said, as long as you're not bottoming out the rim often and the tire doesn't feel like it's squirming in corners/g-outs then don't worry about it.
