That's completely ridiculous for a number of reasons. First, the usage of fact is not regulated by SI or something, it has a number of definitions and connotations. Second, stating that all facts must be stated with tautological and temporal boundaries is beyond pedantic.

"I have two legs at this moment of Planck time, and not before they were formed in the womb and not after any possible incident in the future where I lose one or more legs."

No. If you measure something, those measurements can change. Yes, the new measurements do not overwrite the existence of the old, that's generally understood. If your measurements change, you change clothes. That makes sense.

On top of all that, the original quote is "When my information changes, I alter my conclusions."

I don't disagree with this statement. That's not what was said.
