Talhoffer (famous German fencing master from the 15th century) shows it in his 1459 manuscript but i don’t think there are many more sources for this. It definitely doesn’t seem like this was at all common and as far as i know it isn’t even clear if it ever happened. It might just be an idea by Talhoffer to make a theoretical fight like this more fair.
Could you please link a source?
