What's the difference between "outSAMstrandField" and "outFilterIntronMotifs RemoveNoncanonical"

[hungweichen0327]

Dear community,

I want to ask about the difference between outSAMstrandField intronMotif and outFilterIntronMotifs RemoveNoncanonical.
According to the info. from the STAR --help,

1. outSAMstrandField intronMotif : strand derived from the intron motif. This option changes the output alignments: reads with inconsistent and/or non-canonical introns are filtered out.
2. outFilterIntronMotifs RemoveNoncanonical: filter out alignments that contain non-canonical junctions

Are they the same? But it seems that outSAMstrandField intronMotif not only filter alignments that contain non-canonical junctions but also alignments that contain inconsistent junctions.

Thank you.
