This is untrue. "Shuttering" is/was a common
method of construction of cob homes in the UK.
There is also nothing wrong with straight walls. While curved walls are nice
and have an inherent strength as long as you "close the box", cross
wall, or buttress either/both internally or externally you'll have a very
strong structure.

I think one of the issues is that using forms makes it quite  
difficult to work with curved walls- you're pretty much limited to  
rectilinear design, which is OK, but you lose the inherent stability  
and strength of curves.  You also are limited to using the cob as in- 
fill rather than load-bearing, as you need a frame to attach the  
forms to.
