Should the alternative be more logical ?

To avoid having to press Enter more than once to enter and move a number to the Y register and be ready to accept a new number in the X register.

HP changed this by removing stack-lift disable in the 28C and subsequent RPL machines. RPL approach is definitely more pure and 100% predictable, but RPN approach is more efficient for 'normal' (meaning entering numbers from keyboard) data entry.

There is also a 3rd mode, Entry RPN, but further discussion becomes religious, so I'll just leave it like that.
