Not really, that's just a future tense. Here's the correspondence instantiated:

"I am tall" -> "sou alto" (ser)

"I am broke" -> "estou falido" (estar)

"I am being boring" -> "estou a ser aborrecido" (estar a ser)

What english doesn't have as easily without context is the distinction between the first two forms because it has a single verb for both.
