mistake in tac description

[SpikePy]

Tools like grep and sed have features to easily match the first occurrence, so applying tac on the input helps to reverse the condition from last match to first match

Isn't it the other way around?

Yeah, I think I need to rewrite that sentence.

Without applying tac, the task is about matching the last occurrence. After applying tac, the task changes to matching the first occurrence. This is what I intended to convey, but I can now see how it can be interpreted the other way.
