Why is "pueden" being used in the first example here?

I have this screenshot from Rosetta Stone:

In all three examples, he is talking to one person, so I can't figure out why he says "pueden" in the first example. Are "puede" and "pueden" interchangeable with the impersonal use of "se" or is this just an error?

The impersonal 'se' is always associated with a third person singular verb.

The third person plural can be used in the passive 'se' construction.
