If Wolves had gone early then they wouldn't have even explored Lopetegui would they, so in a hypothetical world he's available for someone else, you don't know how it'll go until you pursue it.
That's the gamble whichever way you go, act early and maybe someone better comes along. Wolves hung on a bit with a particular individual in mind and now he's said no so we've ended up still having this gap. Unless Lopetegui had said weeks ago, when first thinking he was likely to get the sack, that he was planning some time out then Wolves couldn't have avoided that.
