It is a good way to ask the question but I don't think the explanation is on point. These are different questions after all. Someone who needs to save face when asked if content made sense will have not understood the talk. It's doubtfull they'll have anything to add to make your explanation clearer if asked for that, not without again losing face and admitting they didn't understand a certain part. However I do think the rephrased question will invite more feedback from those who already understood the content and themselves are aware of the more bumpy pieces and want to point them out. Those folks are indeed more ready to now provide feedback.
