"Especially in beginner code" seems to say to me that they might be 
copying from beginner examples, especially of the sort that appear in 
Oracle's Java tutorial.  These example are designed to be shorter to 
read on a web page or book page, and don't show best practice or correct 
pattern.  The examples simply show how to use the API.

Also, MVC is not MVC.  That is, most languages and frameworks use a 
modified MVC that really isn't MVC.  Java itself uses a "split model" 
design pattern.  Model-Presenter-Controller is currently a popular 
design pattern which can be used in Java.

"Close coupling" is an anti-pattern in most cases.

Do you have an example we could look at?
