from what i have read no this is still classed as quadpedalism as it is based on which is used for a majority of the time. I.e. chimps are classed as quadperdalism as they use their fists mostly when they walk, but can do small movements bipedally.

and info from other books and work, also suggest this.

Hope that helps
