A small study (reference from KT Park’s Twitter feed –Gastrointestinal Endoscopy DOI: http://dx.doi.org/10.1016/j.gie.2014.10.024) suggests that taking a single biopsy per pass rather than two biopsies per pass results in better quality specimens:

Here are the results and conclusion of the abstract:
Patients (N = 86) were enrolled, 47% with known celiac disease, 36% with suspected celiac disease, and 17% with an unknown celiac disease status. Well-oriented biopsy specimens were noted in 66% of patients with the single-biopsy technique and 42% of patients with the double-biopsy technique (P < .01). Analysis of matched pairs showed improved orientation with the single-biopsy technique (odds ratio 3.1; 95% confidence interval, 1.5-7.1; P < .01). This persisted in subgroup analysis of patients with known celiac disease (P = .02), villous atrophy (P = .02), and a final diagnosis of celiac disease (P < .01).
The single-biopsy technique improves the yield of well-oriented duodenal biopsy specimens. Endoscopists should consider taking only 1 biopsy specimen per pass of the forceps in patients undergoing biopsies of the duodenal mucosa.
