I didn't know there was a Momotaro Gold as there is Momotaro F1 so below I did a Google search and I'm sure by reading the links you'll find what the plant habit is.

I assume that the MGold is also an F1 from all the Japanese links there are,

I am not completely sure but this was a sales page and "rootstock" might be referring to availability of grafted seedlings. Grafted plants are common in Asia.

nothing about "determinate" only "meek vigor"
which could be interpreted relevant to rootstock/scion performance (controlled growth of the scion match is key - you want them producing fruit not lots of foliage and vine)
