Yep. It's a brand style thing probably so they can trademark it.
PS: I had the pleasure of having eusocial Danish neighbors growing up. The guy worked for Spectra-Physics as a laser technician and drove a Wankel '81 Mazda RX-7 that I could hear revving away towards work every morning.
I'm curious how you're using the word "eusocial" here, because I've only heard it used to describe the structure of bee or ant (or naked mole rat) colonies.
Really social, never bothered by anything, absurdly friendly, and cool peeps. And, of course, Scandinavian furniture and always smoking weed. :o)
Stipulative definitions since meanings of words vary from person-to-person:
"Eusocial" to me means "prone to socializing".
"Prosocial" to me means "aware of the interests of the group and seeks to positive contributions to the groups and individuals."
"Asocial" to me means "neural or indifferent towards others."
"Antisocial" to me has multiple meanings either "avoids people", "doesn't get along with people", or "is indifferent to or against the interests of others".

(It also says when you speak the word you're supposed to shout it as if you're scaring off birds. If you look down there on page 11.)
Danes are weird.
