No, it doesn't. If you are at all familiar with the way oil seals are designed, it's obvious why not. Oil seals have a cavity on the oil side, so when the pressure builds up behind the seal it exerts more pressure on the sealing surface, which keeps the oil from being forced out. Your seals don't blow out when compressed, they just get better at sealing.

So why have you always heard that strapping your bike down will blow the seals? How did this often repeated and long standing rumor get started?
Strapping down a bike with good seals will not make them leak. But if the seal is already compromised, maybe there is a piece of grit in there, or maybe the lip is nicked or whatever, strapping it down with the forks compressed will force oil past the already bad seal.
If you arrive at your destination and there is a puddle of fork oil in the pickup bed, the incorrect conclusion you may draw is that tying the bike down is what caused the seals to leak, rather than revealing an already bad seal. Then you tell everyone on the internet and they tell everyone on the internet and here we are with a widely believed ongoing misconception.
