Another lyrical mystery

I was recently listening to Bon Jovi's "I'll Be There For You"... and in the song he sings:

I'll be there for you
These five words I swear to you

Wait a minute... FIVE words? I always thought that "I'll" would count as two words. Doesn't it?
Bon Jovi would definitely flunk college man. He'd exceed the word limit without knowing it.

I'll be there for you
These SIX words I swear to you...

There, much better.
