As per the Esri doc:

It is a common misconception that only tools downstream of a model iterator will run multiple times. When a model contains an iterator, all processes in the model will be run multiple times.

All tools that need to run multiple times should be placed in one model with a model iterator and used as a submodel. The tools that only need to be run once should be placed in the main model, which calls the iterating submodel.

The workaround is to use nested submodels:
