I was reading this Wikipedia article. I couldn't understand the bold part. Did M-W win the case which prevented RH to use the word "Webster" on their college edition but the injunction didn't require RH to not use the "Webster" on their other editions? Is it so? Please help me. Thanks

An expanded second edition, edited by Stuart Berg Flexner, appeared in 1987, revised in 1993. This edition adopted the Merriam-Webster Collegiate innovation of adding dates for the entry of words into the language. Unlike the Collegiate, which cited the date of the first known citation, Random House indicated a range of dates. For example, where the Collegiate gave 1676, Random House might offer 1670-80.

Random House incorporated the name Webster's into the dictionary's title after an injunction won by Merriam Webster preventing its use on Random House's college edition was overturned on appeal. The name Random House Webster's is now used on many Random House publications.
Random House vs Merriam Webster:

1-- MW won; they got an injunction keeping RH from using the name.
2-- Then RH appealed the court decision.
3-- RH won the appeal and the injunction was withdrawn.
4-- RH could use the name.
Thank you, Mr Micawber.
