regex – Why no backtracing when using star with negated character set

Actually i understand what is backtracking, which is the state when the engine applies a greedy quantifier, which result in other atom failure so the engine starts to backtrack to the previous state to give up matchings gradually in the sake of matching remaining atoms.

but i got unexpected behavior when used this pattern "[^"]*" on this "abcv, which i wrote it to check what happens on failure. and i expected the engine to take these step:

• the engine matches "
• then the greedily quantified negated character set will match abcv
• the engine fails to match the last "
• so it should backtrack to the [^"]* to give up characters one by one trying to match the remaining atom.

but when i test this on regex101, the engine doesn’t backtrack, but it starts over from another position each time it fails. so what am i missing here?

Is this what exactly been expected? if so, would any one explain why?

Update

I need to mention that ".*" backtracks and if you check the engine steps you will find that it starts giving characters one by one but the one with issue doesn’t. why this difference while both .* and [^"]* are greedy quantifiers which matched the same text, but one had to back track, the other hadn’t.
