Those pretty much look identical to me. The only difference between a jerk and a [ush press is that you dip twise on a jerk, once to start it and once again somewhere between the bottom and top third of the movement.
I like JV Askem's website. Everything there is golden. Stick to his instructions for the jerk/push press.
While we're at it, he also gives a nomenclature lesson. ALL jerks are push jerks (start with the same dip and push with the legs), a jerk with a shallow dip is simply the "power" version, much like a power clean or power snatch.
