Renzoku

Hello, is there a way to combo a Rashousen from a Raiei Sageki? In the corner I'm connecting a Rensen (FRC), S-Raiei sageki and while in the air I start charging 4. When I land I try to execute the Rashousen but all I get is a 6H. Seems like there's some kind of "artifical" restriction to perform this since the charge time is enough to perform the Rashousen. Thanks in advance.
