I'm on my XPS 13 right now, on Arch Linux using xf86-libinput, thumb rested on the bottom left of the trackpad ready to click. Moving my finger on the trackpad towards the top moves the cursor. Using two fingers (with my thumb rested) scrolls the page. However, if I use my thumb to move the cursor first, this doesn't work and instead scrolls the page. Hope that answers your question.
