This gemara does not speak about the Chosson breaking a glass under 
the chuppah.  It talks about breaking an expensive  vessel to 
decrease the levity of those at the chasanah.

Once the glass (that is not expensive) is broken by the chosson, all 
sorts of "joy"  breaks out to the extent that some rabbonim have 
called for eliminating this practice.  See Rabbi Dr. Ari Zivotofsky's 
article that I posted a link to.
