When अकार / आकार is followed by a प्रत्यय of प्रथमा or द्वितीया विभक्ति that begins with a letter of इच्-प्रत्याहार, then the पूर्वसवर्णदीर्घ given by 'प्रथमयोः पूर्वसवर्णः' does not happen.

Commentary
The substitution of a long vowel homogenous with the first, does not take place when अ or आ is followed by a vowel (other than अ) of the case-affixes of the Nominative and the Accusative.
Thus वृक्षौ, प्लक्षौ, खट्वे, कुण्डे ॥ Here Rules 6.1.87 &c. apply. Why do we say "after अ or आ?" Observe अग्नी ॥ Why do we say "followed by an इच् (a vowel other than अ)"? Observe वृक्षाः here (VI.I.I02) applies.
