Does entire youtube confuse multiple regression and multivariate regression? (Or do I?)

Hi guys,  
I've always learned that basically one response & multiple predictor variables is a multiple regression problem (aka multivariable regression, with multiple variables). Next, multiple response variables & one (or more) predictor variables would be a multivariate regression problem. 

Funnily enough, every single video I looked at on youtube which is said to discuss multivariate regression is just talking about multiple regression. Suprisingly enough, also video's with tags from different universities. (gotta admit after the first few pages of search results I kinda gave up, so it's probably not all videos)

Is this just too niche to be picked up as an error or something?

I also learned that "multivariate regression" implied needing a multivariate distribution for the error term, not just having more than one explanatory variable.

I think the problem is mostly that so few people DO regressions with more than one response variable estimated simultaneously, that the terms aren't in common use. 

Note, in contrast, that "MANOVA" still unambiguously refers to having a multivariate response, because terms like "2-way ANOVA" etc are well known for the more-than-one-predictor case.
