I don't know what exactly your question is. You show us some code, its output, and then just wonder if you are missing something. *I* certainly am missing something, namely your expectation of what the code should do.

But I take an educated guess. You are baffled by the behaviour of \Q and \E. One should realize that \Q and \E are dealt with in the interpolation stage, which happens before a regex is compiled. I refer to the section "Gory details of parsing quoted constructs" in the perlop manual.
