That wiki page seems to agree with you indeed.

It was less of a problem because you just have to say the league doesn't exist and don't have to worry about who qualifies for the CL.
CL qualification existed starting the 1956 season.
This season, it will be a bit more complicated. Who goes through then? The same as last year? That would be pretty bad business for us as we need to be back in the CL.
We need to be top 4 and then they freeze the league to have a good chance. Otherwise, we have to ask to continue (at least from our perspective).
We won't have a say but this is how I see it.
