When you open a console window that is an application. In general the term "shell" can used to refer to this application regardless of OS.
When you run the VM it creates another application.
The shell redirects the stderr/stdout pipes of the VM (or any app run) so that it shows in the window that you see.
That however is not the same as when you type something at the command line.
Depending on the shell, and often on other installs on the OS, and even how the shell is run, certain combinations of characters and create certain activity in the window.
That is more likely to occur and be available on unix variants. Windows will be unlikely to have that (it definitely requires additions.)
One standard way to "clear" the screen is to simply print a large number of empty lines. 120 should generally be sufficient and 240 more than sufficient. This has the advantage that it should work on any system.
