Is a twin born through in vitro fertilization more likely to give birth to twins?

As I understand it, twins are more likely to have more twins. Does this hold true if the twin was a twin because of in vitro?

In a word, no.

There are two kinds of twins. Identical and fraternal (non-identical).

Identical twins form from one fertilised egg. So two babuea from one egg. We dont know why this happens in most cases, but the chances of it happening are uniform across populations. 

Non identical twins are the result of two eggs being fertilised. This can be because the mother has released more than one egg at ovulation, which has a genetic factor. Women with non identical twins in the family and older mothers have a higher % of this happening. 

This is the most common cause of multiples in IVF. But in this case it is artificial, rather than the mother releasing multiple eggs, multiple fertilised eggs are implanted to,increase the chance of taking. So any female children concieved, would not inherit the genes for multuple egg release unless the mother had it.
