Not being a PO is valid reason. :-)
Better from a strength standpoint if both holes are aligned, the same size and the connection is snug, though. But with 10 bolts it's not critical. Same with my ARB, 14 bolts of various size attach that sucker. Worried? Nah. If it was a winch plate on top of the frame horns with 4 bolts, might be more careful.
