I wouldn't say it's a full-out "reference" to the first film based on that. But we can always say:

"On Anna's birthday, the manner in which Elsa roused her sister was similar to how Anna woke her up as children."

I think that's a good compromise :). We note the similarity as a fun fact, but we don't say it's a complete reference to the first film ^^. But of course, I'm open to more discussion :)
