Quote from HUCK
----------------------------------------------------------------------------------
Clomid stimulates L-H-R-H/LH production by binding to ESTROGEN receptors on the hypothalamus and pituitary,thus giving the illusion of a low presence of circulating estrogen.Note the key word here-ESTROGEN.CLOMID DOES NOT BIND ANDROGEN.Therefore,on a cycle of moderate to high amounts of ANDROGENS,clomid will have no effect whatsoever on endogenous testosterone production,as we are in a state of ANDROGENIC inhibition.It's post cycle,when blood levels of androgens begin to normalize and the typical estrogenic rebound/lag occurs,that clomid is able to re-initialize this process of testosterone production

Clomid will cause endogenous test production in the middle of a cycle even on powerful androgens. You say right in your own explanation that it stimulates LH production and that is all you need for endogenous test production.
If you use clomid throughout your cycle, it will prevent testicular atrophy altogether, but upon cessation of clomid after your cycle, the higher than normal levels of test will cause atrophy. There is no way to avoid this period of atrophy after a cycle.
If you use it after cycle, your nuts will already have atrophied and you will need a large dose of clomid to start endogenous test production. There may be some benefit of clomid during a cycle because the HPT slowdown/shutdown will not be as severe, and thus it may not take as long to get normal test levels again.
