Short description of error
Changing the deform or render parameter for this function has no influence on the result:

Exact steps for others to reproduce the error
Open the .blend file, execute the script and look into the terminal. Both vectors should be different if everything is correct. Also both bmesh objects should use render deformation, which I turned off in the modifier stack. The modifier is used anyway.
