Yes, that is exactly the reason. Tv Tokyo only gives Viz(who then gives the subbed version to CR) the original masters. In other words the movie promotion is added later in the broadcast, like how commercials are added. They will not appear on the DVD releases. The reason it takes so long for CR to sub the songs (chAngE was eventually subbed) is because they have to deal with sony music group (who can be from what I heard from people in the industry a pain to deal with) to get the copyrights to the lyrics. It can take months to get the rights. CR is doing the right legal thing, also if they don't do it that way TV Tokyo would likely suspend CR's (and possibly Viz's) license to the series. What SGKK is doing is technically illegal, both with ripping a licensed anime and subbing unauthorized music, but I am not going to talk about that. So basically it's just a licensing issue.
