Ha funny thing, didnt knew about it but it seems legit.
According to MDN (
https://developer.mozilla.org/en/JavaScript/Reference/Global_Objects/RegExp/test
)
"As with exec (or in combination with it), test called multiple times on
the same global regular expression instance will advance past the previous
match."
Here is another example:
var asd = /\$[0-9]{1}/g
/\$[0-9]{1}/g
asd.test("$a$1$2$3$d")
true
asd.test("$a$1$2$3$d")
true
asd.test("$a$1$2$3$d")
true
asd.test("$a$1$2$3$d")
false
Hope that helps
