The answer is not far by answering this question , How do you read the numbers whatever RTL or LTR from left or from right !!! Ex 123 123 or ١٢٣ are the same reading so your assumption is not valid .

So if we have a string that mixes alpha and digit chars owe naturally have a mix of LTR and RTL. What am I missing?

I hope you all doing well, after back to TF-AIDN "Task Force Of Arabic IDNs", I got the following regards to mixing LTR and RTL texts within the same label. - Mixing between different scripts is not allowed for domain names and email addresses - Numbers at the middle or at the end of the RTL domain name is allowed.
To be away from the display issues we get if we mix RTL and LTR code points in the same labels.
Thanks. I think this clarifies the point that we have no advice on displaying e-mail addresses, since mailboxes are not domain names and are not labels and are not subject to IDNA2008.
