I didn't know or realize that the Nasdaq price deficiency is not lifted immediately after a RS:

A reverse stock split increases a company’s share price while reducing the number of outstanding shares. Reverse splits rarely achieve a lasting solution to the bid price deficiency for struggling companies, ultimately resulting in other deficiencies based on the company’s market value when the company’s stock price sinks to near pre-split levels. Therefore, Nasdaq will wait for the reverse split price to settle in the market before lifting the bid price deficiency.

I guess that is why companies have to choose a large enough RS to make sure that when the stock price gets hammered after the RS that it doesn't fall back under a buck again.
