Hang on a sec. This applies to what you have done, not a misunderstanding for someone else. The Practice is clear:

A personal explanation is not restricted to matters of misrepresentation. For example, Members have been permitted to use the procedure to explain an action or remark, apologise to the House, clarify a possible misunderstanding, state why they had voted in a particular way, and correct a statement made in debate.

It's not applying to someone else. So you've got to explain where you have been misrepresented, or where the mistake is that you've made.
