Yes this is true but I would hope not to have to do that 
I suppose it becasue of the bad problems I've heard ppl of run into with dynamic disks.
How does it work from the point of view of having to rebuild the server. If I had to rebuild the VM or redirect the disks to a new VM, does Windows pick up the dynamic disks in order correctly if they are all presented correctly ?
I suppose the other question is moving forward that once a dynamic disk which is stripped is made then if ESXi did increase the 2TB limit I wouldn't be able to change to a simplier setup. As where if I start with the 2TB basic I still have the choice when I reach that limit to either go multiple 2TB VMDK or just increase the current 2TB VMDK...??
