Not exactly what it says. It says it uses 7 minutes of power in the first 5 minutes. However, lamp life is shortened by 20 minutes every power on, so that is the reason for the 20 minute recommendation.

I am unable to find anything else to support the claim about 7 mins power in 5 mins.

That's only if the warm up cycle of a fluorescent bulb is efficient. The claim could be spreading that energy over the whole 5 minutes.
