A very uncommon scenario is someone only aquiring tickets for other attendees.
Describe the solution you'd like
Therefore, it seems fitting to allow the 'Your Details' to be also used to populate the 'Attendee 1 Details'.

When going through the ticket purchase process with many people quickly, I found it time consuming and error-prone to enter the details twice.
Some attendees didn't recieve tickets bevause they misspelled their email the second time.
