From my experiences, I think most people have quicker recovery on the smaller muscle groups ie: arms, chest, shoulders and therefore can bench or press or arm work/grip 2x maybe 3x per week and make good to great progress using regular small additional amounts.
The larger groups, like hams, glutes, (or it might be better to say the entire posterior chain) can see good improvements with as little as 1x per week, (at least heavy) say squatting or deadlifting. Then possibly lighter work or iso work on those groups like quads, hams etc. a second day in that same week.
A few caveats, even though the lats are a large group, it does not necessarily take the level fitness to complete a set of chins or rows or pulldowns, compared to what it does to complete 3x5 in the deadlift, or 5x5 in the squat. So that can be another reason guys can get more frequency from those exercises as well.
