Q. Re question 2450 above. - One who forgot to request mashiv haruach, and he already passed the bracha of Retzei, and then went back only to Shema Koleinu and mentioned it there, is he yotzi?
A. Horav Shlomo Miller's Shlit'a opinion is that even bedieved, if after forgetting to mention mashiv haruach at the second brocho, one did not return to the beginning of the amida as required, even if one mentioned mashiv haruach at shema kolenu, one does not comply.
The reason being is that, as opposed to "vesen tal umotor," that is a request and part of the tefilos included in shema kolenu, mashiv haruach is not. It is only a hazkara or testimonial praise to Hashen, that does not belong in shomea tefila.
