Is there a situation where there are too many logical modules that cannot fully cover MCDC?

No, it does not. Because the input of the Multiport Switch is fixed to 1. Any coverage is not measured unless the path leads to the output of the model.

In case of Multiport Switch I demonstrated,
- Change Constant value to 1 ("Constant" is the first input of the Multiport Switch)
- Input all combinations to the topmost AND block
- Change Constant value to 2
- Input all combinations to the second AND block
- Change Constant value to 3
- Input all combinations to the third AND block
- ...
