initial stream id from a client

Please let me clarify the initial stream id from a client written in draft-05.

In 5.1.1 Stream Identifiers,
" A stream identifier of one (0x1) is used to respond to the HTTP/1.1 request which was specified during Upgrade (see Section 3.2); stream
identifier 0x1 MUST NOT be used by a client to establish a new stream. "

Is 0x1 always reserved for the implicit stream so that a stream from a client
should start from 0x3 even in a TLS connection?
And if a server receives a stream of 0x1 from a client, is it a connection error?

Or is it only the case of upgrade?
