Zoom in, drop out

On reading the interesting research on droplets ("Dial-a-Splash: Thin air quells liquid splatter," SN: 2/12/05, p. 99), I noticed that the two droplets shown in the photos at the moment of first contact have different shapes. In air at normal pressure, the droplet has the characteristic hamburger-bun shape. In contrast, the droplet at reduced pressure is spherical, or nearly so. Can this difference be responsible for all or most of the difference in the splatter patterns?
