You got next 20 posts:
51450914667
51439618771
51439359109
51439149930
51438948039

51370163416
51370155416
51348879503
51348709311
However, there are two posts in-between:
51460950351
51460948891
are missing.
This is definitely caused by pagination, as if you just change the before timestamp to a little bit earlier, they will appear just fine:
E.g. change before to 1369642261:
51460952445 <--- posts from call #1 (second-last)
51460951105 <--- posts from call #1 (last)
51460950351 <--- missing post #1
51460948891 <--- missing post #2
51450914667 <--- posts from call #2 (first)
