Why wouldn’t it be odd? Well, if Mary had been born without sin, she would not have needed a savior, particularly when the claim is made that she remained without sin. So, logically:
If Mary is sinless, why the need to be saved from sin?
If Mary is a sinner, needing a savior, then she was a sinner.
See my earlier posting referencing Luke where SHE STATES that Jesus is/will be HER savior.
Can’t have it both ways.

What if Jesus preserved her from sin?
