Appium tests are executing even with the wrong Capabilities

I’m trying to execute Appium Tests on Samsung Galaxy S3 with 4.3 Android Version. My device name is GT-XXXXX, and version 4.3 .I have given capabilities as below,
DesiredCapabilities capabilities = new DesiredCapabilities();
capabilities.setCapability(CapabilityType.VERSION, “5.0.2”);

But my tests are executing on the same device with no errors.Let me know if we want to connect more devices and try to execute tests parallel , how they could be executed and what are the changes needed.?
