I think much of this has to do with the skill and training of the provider.
In Austrailia they did a fairly recent study on low risk for hemorrhage population and the active management group were 7-8 times as likely to have hemorrhage .Additionally the majority of the active management studies were in clinical settings before the delayed cord clamping studies showed benefit to babies to delay cutting the cord.
Perhaps have ypur mom look at this study and the review.

"CONCLUSION: This study suggests that 'holistic psychophysiological care' in the third stage labour is safe for women at low risk of postpartum haemorrhage. 'Active management' was associated with a seven to eight fold increase in postpartum haemorrhage rates for this group of women. Further prospective observational evaluation would be helpful in testing this association."
I think it takes quite a while for research to alter practice on a world wide level so in recent years the older studies influenced WHO to recommend active management, but there have been problems in having pitocin on hand to accomplish this,and not enough trained professionals to do it as recommended in the older studies, so they have been experimenting on 3rd world populations
Trying to figure out if no pit will work they are also looking at using misoprostol for this, to confound this movement is the info about delayed cord clamping being healthier for babies. No absolute newer protocols have been figured out. I do think there are more studies underway in OZ like the one above. So keep checking pub med.
Here is one Review reference, they included 4 studies, their conclusions were things like babies weighed less in active management group due to quick cord clamping and there were more returns to the hospital for bleeding( which means over all blood loss probably not any better, but they would have stopped measuring blood loss)
