Shape of phase plot(U-S) changes after scv.pp.moments(adata)

Hi, thank you for developing this tool.
I have a question about the shape of a phase plot
Before calculating scv.pp.moments,
scv.pp.normalize_per_cell(adata)
scv.pl.scatter(adata, basis=['FTL'])
and this is consistent which I checked through my own code doing total count normalization
but, after doing
scv.pp.moments(adata)
phase plot dramatically change, like below,
why is this happening?
and which is a correct phase plot?
Sorry if this is a question lacking an understanding of scVelo's essense,
but I would appreciate it if you could explain why this is happening.
Thank you,

Please check the docs for these sort of questions. If moments exist, scatter
plots them by default.
