yes you got exactly the biggest disadvantage of this tongue and groove decking. The same is true for camo hidden fastener and the ipe clip extreme (double groove system).
The second issue is the ‘working of the wood’, if it extends, where does it go to? Therefore you should always use regular decking with stainless steel screws and between the boards a spacing of 4 – 5 mm
