He didn't mean his own death, necessarily. But the death of older physicists that founded previous revolution stuck with the old (and wrong) ideas that were against his new (and right) ideas.
You'll find that historically, older scientists in prominent positions will be adamant against an uprising revolution in his field. If he/she wields enough power in academia, he'll crush it...at least delay it for a while, until he dies.
Newton was rather notorious for this sort of stuff. He held some high position(forgot what it was called) in academia and made it difficult for lots of other younger scientists that came after while he was in power.
In reality, the first is true, even for Planck. He'd be a fool not to realize it too. I didn't mean to say Planck's right forever.
Phrased another way, I don't think his point in saying how science progresses by funerals is to point to his own death. It was to highlight the misconception that most people have that current science theories come to prominence in science because the revolutionaries changed the minds of the old guard through proofs and experimentation. Rather, proof and experimentation changed the minds of young revolutionaries, and only when old guards die off, the revolutionaries rise to take their place and make prominent the new theory.
