Another perspective from the Choy Li Fut side.
One of the Ten Seeds, the Na/La 拿 bridge, is a core piece of CLF's snake form.
拿 means to seize with the hand (not exactly "shooting fingers" like the Wiki says) but it's executed as biu ji techniques (definitely means darting snakey fingers) for a reason, that last inch doesn't have to be a strike the way Lee did it, it could be a grab. It could be a strong push, too. It could be chest to chest. It's all still the same one inch bridge.
You'll also see Southern family Crane techniques in this video, because like a lot of animal forms, they tend to mix in animal energies that go together like Snake and Crane. I always find it helpful to compare things like Wing Chun and CLF, you can see where Wing Chun has lost some of its mobility compared to the broader, deeper styles.
