Explain python slicing issue

As we know 

seq[::stride] = [seq[0],   seq[stride],     ..., seq[-1] ]

But when stride become negative then

seq[::stride] =[seq[-stride], seq[-2*stride], . . . . ]

Why is the latter case not like [seq[0],seq[-stride], . . . . ] ?

Because if the stride is negative, the slice always automatically starts from the end and goes backwards.
