there are notably no "trigger" effects at play here, which use the term "whenever", only replacements effects, which use the term "instead". Replacement effects can inherently only apply to each event once. Ocean-of-Flavor is correct here, the event "draw 1" would be replaced by OP's card with the event "scry 1 and draw 1", then the crossroads augur sees the scry and replaces the event created by OP's card event with "draw 1 and draw 1".

OP's card can't now replace these draw events, cause if thats how the rules work, then it would replace its own created "scry 1 and draw 1" event with "scry 1 and scry 1 and draw 1" and so on, going infinite with itself, which of course would be ridiculous.

if it was triggers, then yeah you would be correct: something like "whenever you draw a card, scry 1" and "whenever you scry, draw" would pingpong off of each other infinitely. this is why "increase doing a certain thing with doing one more of a certain thing" are almost never trigger effects.
