Wondering if someone can help me with a question on quoting references. If you have two separate points in a paragraph by the same author, do you reference both, and do you write the reference same way?

This is an example of what i mean:

Elephants are big animals with four legs and a large trunk (Smith et al., 1998). Giraffes are tall animals with four legs and a long neck (Smith et al., 1998).

Is that the way you would do it?

Thanks,
