Not the same thing. They did not fall as dead men, but continued to stand.
Transfiguration still did not reflect the glory He received after His ascension to the right hand of the Father....it was before His death, burial and resurrection - and before His ascension.
John saw Him in Rev. 1:12-17 AFTER He had been fully glorified.
And, even though he was the “disciple Jesus loved”, and had laid his head on Jesus breast at the Last Supper - fell as a dead man.
The Same One as Daniel as he wrote in Dan. 10:4-10, eh?
