Kacc 10 & 11 Redux

I revised my translation of 10 & 11 last night, in response to Ole's comments.
---------
1‧1‧10
[A word] having been before, [the adjoining leading letter of the
other word] with [its] vowel may be separated and set below.
Thus the euphony is undertaken with the previous consonant "set
below", having made the other vowelless and having made the [next
syllable's] vowel separate on top.
[Example:] "Tatrāyamādi."

1‧1‧11
The adjoined leading [letter] of the other [word]… [cf., 1‧1‧10]
[Note: the subject of rule ten is in fact provided by rule 11; in
private correspondence, Dr. Pind observed that the order of the rules
was somehow reversed in their being adapted from the Vararuci's
Prakrit grammar, the Kātantra, 1:1:21-22.  Again, the commentarial
layer is at odds with the meaning of the verse:]
The other word's consonant that stands below [viz., was set below] is
joined to the leading letter opposite.
[Example:] "Tatrābhiratimiccheyya".
Why is this joined? [Example:] "Akkocchi maŋ avadhi maŋ ajini maŋ
ahāsi me." In this example, joining is not necessary.
