求帮忙看看WPI的回复是什么意思？

我问了问小秘能不能申两个专业，如果能的话互相影不影响，小秘火速回复了如下内容：
Good morning Miss Zhang,
Thank you for your query about the WPI Data Science program and your wonderful analogy.
.1point3acresYou may certainly apply for both programs simultaneously and no, each program doesn’t see  the other’s applications.
Everything is digital.
Should you at some time decide to transfer to the other program from the one you have initially chosen, you would
need to re-apply and then transfer any applicable courses.
I have included the DS curriculum committee in my response to you, in case they have further information for you.
I hope this answers your question.

那么问题来了。。Should you at some time decide to transfer to the other program from the one you have initially chosen, you would
need to re-apply and then transfer any applicable courses.这句话是什么意思。。。看了半天没看懂。
谢谢各位大哥

意思是你被录取了A之后想去B
你得重新申请
录取了之后可以把applicable courses转到B专业去
