No it's because they ran out of spell names. I know in english it is just Stone I - IV, but in other languages the spells have specific endings. In german it's -ra, -ga, -ka for example, I don't know the endings in other languages. These endings are used in basically all Final Fantasy games and Yoshi did not wanted to invent a new ending for the spell names.

It's also likely the reason why we jumped from Glare to Glare III / -ga, so we could end on level 100 with the -ka ending.

Right it's Stone, Stonra, Stonga, Stonja in Japanese too, but they dodged that problem for BLM by adding High to the name and calling it High Fira and such.

Also YoshiP's joked about going to -gyo suffixes, which Amdapor canonically debated on using vs the -ja suffix for CureIV, according to one of the books found in Gubal Hard.
