In theory, it should. Saw several bros from my NH class in my 15.G.4 drafted upgrade class last spring encounter that scenario. We had a system bid run right after we started 145 training in April. Some were sent right back to the line on the 175 as an FO, at least one was forced to complete 145 CA training only to go right back into the schoolhouse for 175 CA transition within a week of his Fed ride. If you haven’t entered training yet, I would hope they are smart enough to just leave you where you are, but that doesn’t seem to be the MO with this place a lot of the time.
