Another perspective from the Choy Li Fut side.
One of the Ten Seeds, the Na/La ć‹ż bridge, is a core piece of CLF's snake form.
ć‹ż 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.
