total-parameter for Page.getVersionHistory is incorrect

The documentation for getVersionHistory() describes the "total" parameter with: iterate no more than this number of revisions in total

This might be interpreted as getVersionHistory(total=25) would result in a revision list with len()==25, but that appears to not be the case. The attached test script prints out lengths that instead suggests the number of revisions returned equals sum(range(total+1)) (the sum of integers {1,2,...,25} is 325).
