The array of arrays it returns does not contain all subpatterns, it only
contains the least hungry match possible in a one element array in a one
element array array.  In a regular match, it returns the hungriest match in
a String.  You're explanation doesn't shed any light on that.

irb> a.scan(regex)
[["\\\""]]                 # this is strange result - $& is what I expected
in some way in result
irb> print $&
"\"hello\""nil           # this result is the hungriest match
