This seems odd to me.

Type M mortar has the strongest compressive strength at a 28 day
strength of 2900 psi, minimum.  While Type S mortar has a compressive
strength of 2100 psi, minimum.

The mix ratios for the different types are as follows:
Type M: 1 Portland Cement, 1/4 Lime, 3.5 Sand
Type S: 1 Portland Cement, 1/2 Lime, 4.5 Sand
Type N: 1 Portland Cement, 1 Lime, 6 Sand
Type O: 1 Portland Cement, 2 Lime, 9 Sand

Mortar Types for Classes of Construction are:

Type M : Masonry subjected to high compressive loads, severe frost
action, or high lateral loads from earth pressures, hurricane winds, or
earthquakes. Structures below or against grade such as retaining walls, etc.
