 The <dfn abstract-op>writeEncodedData</dfn> algorithm is given a |rtcObject| as parameter and a |frame| as input. It is defined by running the following steps:
-1. If |frame|.`[[owner]]` is not equal to |rtcObject|, abort these steps and return [=a promise resolved with=] undefined. A processor cannot create frames, or move frames between streams.
+1. If |frame|.`[[owner]]` is not equal to |rtcObject|, skip to step 4. In this case, either frames were created or moved between streams.
 1. If |frame|.`[[counter]]` is equal or smaller than |rtcObject|.`[[lastReceivedFrameCounter]]`, abort these steps and return [=a promise resolved with=] undefined. A processor cannot reorder frames, although it may delay them or drop them.
 1. Set |rtcObject|.`[[lastReceivedFrameCounter]]` to |frame|`[[counter]]`.
 1. Let |data| be |frame|.`[[data]]`.
