Men tend to push the pace harder, which stretches out the pack, while women are more likely to be content to run in a pack at a less demanding pace. I don't think women are less coordinated, they're just racing under conditions that make contact more likely.
The El Guerrouj fall in 1996 and Uceny fall in 2012 (and 2011) came in almost identical conditions. Pack was bunched up and both appeared to get tripped from behind (obviously in the El Guerrouj case, as you can see his knee suddenly come up).
It might be that women settle into a slower (bunched up) pace, or it might be that with less testosterone, women simply can't sustain a faster pace (and kind off it) as easily. Could also be that women never had a Hicham starting to wind up at 600.
Morgan has been doing a lot of racing in Europe, so I don't think experience is a factor, but it might come to pace sensitivity. If you sense that the pace is slow, there is no reason to settle in the middle of the pack and take risks: You can go right behind the front like Lagat or close to the back like Manzano did (riskier because you might not be able to respond to a big move).
Maybe women always race the same way, while men don't, so there may be more sensitivity to different paces.
