It is not common to shear "while lambing" in the sense of lambs arriving during the shearing process. Is this what you meant?
But shearing just before lambing is fairly common. It is supposed to make the ewes much keener on finding shelter (for the lambs), whereas ewes with a thick coat don't care much about shelter. It also makes it easier for the lamb to find the udder. And it can improve wool quality (complex story involved here).
Problems can arise if the shearing is delayed for any reason, such as poor weather at the planned time - shearers won't shear wet sheep. Or the shearers might have been delayed at a previous farm for some reason so they turn up late. With the odd lamb arriving before the due time this can end up with lambs born during shearing, but it was not necessarily planned that way. A shortage of shearers makes it harder to move shearing time if there are any delays.
Shearing straight after lambing is not common and is rarely planned. Most people leave them all alone at least until they get to know each other. Very young lambs might not recognize their mums with all the wool off. However, shearing more than 6 weeks after lambing but before weaning is possible and sometimes done because of difficulties in getting shearers at other times.
