Exactly, this is the core issue. It also doesn't only happen when the onewheel runs out of juice.
There are endless reports of it just having some sort of control fault and blipping for an instant (I've experienced this myself, thankfully at low speed). A tenth of a second blip at 20mph = instant launch.
Ironically, the other end of the energy spectrum also gives onewheels trouble. If you charge your board too much (leave it plugged in without discharging it), the battery cells become unbalanced, leading to similar blips. This is a known issue - when I reported it (still under warranty), the support rep had a script for how I could fix the issue.
