Questions about simplefoam

I am relatively new to OpenFOAM and I have a question about the solver simpleFoam. I am using OF 2.1.1.
I read a little bit about the solver and algorithm and had some understanding of it. One thing confuses me though. In the source code of simpleFoam
solve(UEqn() == -fvc::grad(p));"
why is there a "sources(U)" term in the UEqn and it is even a function of U? And what is "sources.constrain(UEqn())" for?
Any help will be appreciated.

Digging it in doxygen you first get to IObasicSourceList which is a derivative of IOdictionary and basicSourceList. In latter you find operator() and constraint function:
However in operator() code addSup does nothing according to:
In case it was set to something else constraint clips it in a defined range.
