Hi Aditya,

Actually, they should have the same boundingbox, the first MPdrawing
environment draws a line from (0,0) to (2cm,2cm) and the sequence MPdrawing
environments just add two lines that are in the previous boundingbox.

I know what's happening now. \definesymbol doesn't define a symbol
from \getMPdrawing at once.
