No. It obfuscates the meaning of your sentence and impedes thought flow; especially in the case given, which I would rewrite completely for clarity.
[ironic] Edit for Clarity:
I say that it confuses and makes understanding your sentence more difficult because I couldn't even tell how I was supposed to read the sentence at first. I actually thought it was a fragment. I had to re-read it a few times before I figured out what you were trying to say.
I say that it impedes thought flow because it breaks me out of your story; it totally distracted me from the interesting, relevant, first sentence about the 'thesis'. Granted, it would have been less distracting if I had immediately understood the sentence, but when I say that I would rewrite it for clarity I mean that I personally would probably reorganize the setting information out of the middle of the dialog.
