Doubt on handling non-terminating error

Hi,

I've been reading "The big book of PowerShell error handling" since Don Jones indicated it to me.

On page 9, the author says:
"A value of SilentlyContinue only adds the error to the $Error variable; it does not write the error to the Error stream (so it will not be displayed at the console)."

So I'm trying to do this on Office 365:

It wasn't supposed to have 1 error?
Try/Catch/Finally won't work since it's a non-terminating error.
