Your condition is just fine.
[try Cover=BarsSince(Short)==7 ; to confirm that it works]
But, if Close>Ref(High,-1) comes before the 7th bar after Short, it
is activated first.
For ^NDX there is a [rare] example between 2/2/2001 and 13/2/2001,
when Close>Ref(High,-1) did not happened any of the 7 bars and
BarsSince(Short)==7 was activated first.
You join with OR your Cover conditions, which means you search for
ANY true, not for both.
