What Does A Black Marker Across A Wax Box Mean?

I recall some discussion here regarding wax boxes with black marker across the top. To those "wax experts" out there, what does this mean/indicate? Something about the box being pulled from a fresh case? Less likely to have been searched? Etc.? But I'm not sure. Here's an example:

Raw: Tony Gonzalez (low #'d cards, and especially 1/1's) and Steve Young.
Thanks for the link and great explanation by diamondman. In other words, I read that as stay away. Thanks.

What were they? Jackson 5 cards? Thriller? Scans?
<< <i>Dear Jeff,

Jack,
I would not say stay away, I remember buying full cases of x outs , 84,85, 86 ,87 Topps FB for 100 to 200 a case back in the late 80's and early 90's and single boxes and partial cases, more than not the boxes were fine and would yield the stars, but sometimes the packs were rough and would yield only PSA 7 or 8 quality. I would just not pay as much for X outs as I would a fresh mint box from a sealed case. I know this this doesn't help now with the 86 Fb Box at the start of this thread as the auction is over now, but that X out box looked pretty sweet compared to some I've seen. Hope this helps you in the future. also what onlyanumber a number said odds can be better or worse on an X out.
Thanks for the further clarification. It is much appreciated. I'm not sooo concerned about pulling a PSA 8, PSA 9 or PSA 10 out of a wax box. I just like to know that I have a decent chance. Someday, I'd like to pick up a 1986 Topps Football box. But I'm not in any hurry. As most people know, those 1986 Topps Football are ridiculously tough. But if you can find a nice one, they sure look sweet.
