It wouldn't blunt the saw the first time you did it.
By the time you'd felled the first one, it wouldn't be cutting as well on the second, whether you ccould actually notice it or not depends on just how muddy/gritty it is and what you
consider to be blunt.
We've been on some birch round a lake recently where it was dulling off and stretching chains enough to need to fettle it before you had ran a full tank through.
