Ques No 1 : Is it Compulsary to use only ~=0 condition out of 3 default conditions given in the switch block in a model?
Ques No 2: Is it against the guidelines to use the other two criteria, U2> threshold, U2>=threshold?

To satisfy the MAAB guideline, drop in a relational operator block and a constant just prior to the switch block's middle input.
Representing the relational operation with blocks rather then having this "more advanced" configuration tucked inside the Switch Block will be more aligned with the general spirit of the MAAB rationale.
"It is easier to understand specifications when the configuration is applied with Simulink Blocks ..."

I was not a member of the committee that established these guidelines, so I cannot fully answer your question.
But my understanding is that MAAB Guidelines are similar to MISRA rules/guidelines.
They were put in place based on a history of prior mistakes that required a lot of effort to correct later. The high level concept is that these practices will reduce the frequency and cost of mistakes.
