Issue with Account History params

I am calling the get_account_history from the nodejs Steem package using

steem.api.getAccountHistory('user',-1,100)

which I expect to get back the first 100 items based on the API guide.

params: account(string), from(uint32_t), limit(uint32_t)

The result seems to return 294 which is the total account items. If I try to pass say 'name',290,200 via

steem.api.getAccountHistory('user',290,200)

I would expect to start at the 290th item and show the 5 from 290-294 but it returns the entire history again.
