When a password reset email is sent in an RTL language, the mix of numbers and Latin letters in the password may get mixed up. This is very confusing and it prevents the user from logging in, unless the user is experienced with copying and pasting in messed-up RTL emails.

Since we cannot be sure that the email client correctly guesses that the email is RTL (even the most modern clients frequently fail at this), the safest and simplest way to fix it would be to put the password on a separate line.
