It really seems so.  To be sure I've restarted emacs, turned on rcirc,
and then the activity indicator frequently switched back to [] (i.e.,
rcirc-activity was somehow switched to nil) as I've reported.

But as soon as I evaluate the definition of `rcirc-record-activity'
using C-x C-e, the resetting of `rcirc-activity' to nil doesn't happen
anymore.  That's absolutely reproducible.
