The 75% reduction is applicable only when using Allowable Stress Design method . The loads should acting on only one axis at a time.
The .8WL combination is used in Strength Design Method.

Kind of an elementary question, but this is the first time I have had to deal with this. ASCE Case 3 wind loads are 75% of the design wind loads acting on both axes at the same time. Is this 75% of the factored wind load in the load combinations. For example load combination 3 uses .8WL. For Wind load Case 3 would the factored wind load be .75WL or (.8x.75)WL.
