It is possible the software over-estimated that tree. In rare cases with two trees that are very close together the software will assume the entire cluster to be one tree and hence measure to the ground level from the low ground point of the cluster (assuming the trunk to be in the middle of it). If that is two trees close together it could be over-estimated. I usually can tell there are two trees together by looking at a side profile of the point cloud. However the Zoar Valley LiDAR is an older set that has low resolution and virtually no trunk points were captured. It is most likely a single 150' class tree though, but possible it might be a glitch.
Attached is the area on the boundary of the LiDAR where you found a 161' tulip. I do see one hit that is nearly 162'. And another further to the north that is 155'. See attached height ramp map.
