Sigma and Pi bonds

I am confused by the notation when you determine the hybridization of bonds and lone pairs
an example was this: sigma(C2sp2, C2sp2) <=from the practice final exam on chem community
How would you write the notation if a double bond existed in the same place? Why is there a 2 in front of sp2?

If there was a double bond between the two carbons you would write: sigma (C2sp2, C2sp2) and pi (C2p, C2p). The 2 in front of the sp2 indicates what shell the electron belongs to.

Hope this helps!
