ArcGIS distanceTo script

distanceTo.py

import arcpy

# Variables
pointData = 'points'  # Point dataset
distanceData = 'other_fc'  # Distance to this dataset
arcpy.env.workspace = r'C:/Users/myUser/Documents/GIS/new_data.gdb'

# Create a new field name, and add it to pointData
distanceField = 'dis_' + distanceData[:4]  # Gets first 4 letters of distanceData
arcpy.AddField_management(pointData, distanceField, 'FLOAT')

# Get geometry of distanceData
lCursor = arcpy.da.SearchCursor(distanceData, ['SHAPE@'])
for lines in lCursor:
    lineGeometry = lCursor[0]

# Gets total number in pointdata for status updates
totalNumber = int(arcpy.GetCount_management(pointData).getOutput(0))
countNumber = 0

with arcpy.da.UpdateCursor(pointData, ['SHAPE@', distanceField]) as bCursor:
    for points in bCursor:
        pointGeometry = points[0]
        distance = pointGeometry.distanceTo(lineGeometry)  # Actual calculation of distance
        # Calculate and print status
        countNumber = countNumber + 1
        percentNumber = float(countNumber) / totalNumber * 100
        print(round(percentNumber, 2), "% completed. Distance is", distance, "meters.")
        # Update new field with distance
        bCursor.updateRow((pointGeometry, distance))

Is the distance unit controlled by the spatial reference? I am testing this out and it seems like the returned distance values is not what I had initially expected.
