Does Simulink ignore the values of the parameters of the blocks in the diagram while detecting algebraic loops?

It appears that Simulink detects an algebraic loop by analyzing the structure of the model but not the parameters of the blocks - see the screenshot below. The algebraic loop was detected and visualised by typing in the command line
Is this correct? And is this desirable? In this case, there is in fact no algebraic loop there.

The input of the SUM block are taken from output of the sum block - which is why you are getting algebraic loop problem, as at the first time step, there wont be any output from sum block. Hence, simulink usually takes default value (0) in such cases.
