Commentary
The स् is elided before an affix beginning with झल् consonant (all consonant except semi-vowels and nasals) when it is preceded by a अङ्ग (stem) ending in a short vowel.
As अकृतः; अहृथाः ॥ Why do we say after a short vowel stem? Observe अच्योष्ट, अप्लोष्ट ॥ Why do we say 'after a stem'? Observe अकृथाः, अलाविष्टाम्, अलाविषुः अपाविष्टाम् and अपविषुः ॥ Why do we say "before an affix beginning with a jhal". Observe अकृषाताम्, अकृषत ॥
This lopa is also of the सिच्, therefore not here द्विष्टरां, द्विष्टमाम् ॥ Here to the word द्वि is added the affix सुच् 5.4.18, and then the comparative affixes तर and तम with आम् (V. 4. II). This स् is not dropped.
